Components sometimes disappear

I'm using Swing components (JFrame, JToolBar, JTable etc.). And when I run my application, sometimes (!) only frame is visible -- to make other components visible I need to change frame size -- well, in fact only clicking on frame's border is sufficient. What could be the reason of that?
greetings :)

What could be the reason of that?There's a bug in your code.

Mouse pointer will sometimes disappear

mouse pointer will sometimes disappear

I think dissapearring mouse cursor has been a bug since 10.4. happens to me every day regardless of whether i am using a computer with more than one screen or not, and regardless of the mouse being used. I agree that the problem has gotten much worse with 10.8, with both wired and non-wired devices.
after much research and thousands of dollars invested in different mouse softwares, input devices, and monitors, I have determined that old simple wired input products are better. wi-fi is getting worse. the less amount of monitors are better. apple brand input products are the worst, but more importantly, are not entirely at fault.
I would suggest anyone suffering from disapearing cursors, that are not wifi, bluetooth, battery, monitor, software, web browser or website related, contact apple and complain. lots.
personally, I think this is a marketing bug, eventually apple will be entirely touch based, the only true method of eliminating mouse disapearance is to eliminate mouse and cursor altogether. to assist that future of marketing, bugs like this will proceed to worsen.

Desktop files are sometimes disappearing.

When I start my computer my desktop files are sometimes disappearing and when I tell the computer to organize the desktop they will return. I have been using Mac's for 15 years and never have I had this problem until I updated to OS X Mountain Lion. Can anyone tell me how to fix this. Is it possible this problem is because I use two monitors?
Thank you for any help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Downloaded files won't open, and mouse sometimes disappears

Hey there,
I've just been having some rather minor problems with my iBook, and I thought maybe someone could help me out.
First of all, my iBook won't open a lot of applications that I download. It says that it can't find the application to open the programs with. I looked on a few of these forum threads, and it said to download the Stuffit program. I dowloaded the latest version, but when I went to open it, my computer gave me the same answer as it did for all those other apps- that it couldn't find the application to open it up with. I went back and downloaded the previous version of Stuffit, but that had the same result. How can I get files to open on my computer?
Also, sometimes while I'm in Safari, the mouse arrow completely disappears until I either scroll over a picture or click the back/forward arrows. Anyone have any ideas on why this happens? It doesn't really do anything bad, it's just annoying.
Well, thanks for reading this, and have a good day!

Ok, maybe this will lend some insight to the Safari cursor behavior.
I was on the Slashdots' main page. I had not experienced the issue since yesterday.
I proceded to follow this link, opening it in a new tab:
http://www.crn.com/sections/breakingnews/dailyarchives.jhtml?articleId=188701694
When on that page, the cursor would start rapidly switching from a pointer to a hand. I clicked on the tab for Slashdot. Problem gone! I tabbed back to the CRN page in question and reloaded it. Problem is back. To clarify, I did not have to reload the page for the problem to persist, it was just something I tried.
I emptied the cache and reloaded. No change.
I would like to add that this in no way interferes with productivity when working in Safari, it's just really odd is all.
Any ideas?

PS CS4 menu bar sometimes disappears (parts of it)

Now and then, part of my menu bar disappears - the section just to the right of "help" - I think the first icon for this particular bar is to open Bridge. I've included a screen shot of my issue - notice that area seems to show my desktop (or whatever is open behind PS). I think this has something to do with my graphics card. I have a nVidia GEForce 9500 GT (driver version 6.14.11.9107 from 9/27/09). The driver is current. When this issue comes up, I have to literally reboot for that secion of the menu bar to reappear. Simply logging off and back on doesn't do it. When this menu bar section "does" appear, when I mouse over the icons, the "roll over" icon is blank - or just solid grey. I don't think that is how it's supposed to look.
I've also had trouble (recently and in the near past) with my "show grid" setting (reference: http://forums.adobe.com/thread/493932?tstart=0). For example, I would create a document 72px x 72px @ 72ppi - make my grid visible (grid settings are set to show 1 grid line every 1px & 1 subdivision). When zooming into any corner of the image, I could see the grid lines were offset (example images on my reference post) - this is not to be confused with the pixel grid. I'm wondering if these issues are related to each other and/or because of my graphics card. The grid line offset issue was previously fixed by deleting my preferences, but sine this is happening again, my guess is something is causing the "grid" to show improperly. I've tested with and without GPU enhancements enabled in PS preferences. I just can't find a common thread in which causes these issues.
If I still have your attention, I would like to add an "off topic" issue (maybe somoene reading this can help on the other issue too). In reference to http://forums.adobe.com/thread/508982?tstart=0, no one has really been able to answer this or confirm/deny they get the same results. This has to do with viewing document size, and the unit of measurement seems to get stuck on cm (I want it to remain on inches like it always did with CS3) - maybe I should go back to CS3. Whenever I have rulers set to pixels, the document size locks to cm. The only way I can see inches in document size is if my rulers are set to inches. To me, it makes sense to have rulers set to pixels (for many reasons), but when it comes time to print, change canvas size, etc., I want to see the document size in inches. I don't know if this is normal, but when I go to create a new document, in the preset drop down list for "default photoshop size", it's unit is cm. Could that have something to do with my cm issue? I'm already made sure my regional settings are US, and unit settings are set according to attached image (unitSettings.jpg).
At this point, I'm going mad because these little bity querks just drive me up the wall to the point I can't get anything done because I'm always troublshooting.If anyone can shed some light on any/all of these topics, you would save me from slicing a wrist or two Thanks...

Are you having rendering issues with other software or just with Adobe PS CS4?
At the moment, I'm not really using any other programs which would call for any rendering. Videos seem to play fine, so other than PS, I'm not using any other programs.
Did you update CS4 to 11.0.1?
I just did, so I guess I have to play the waiting game now. The roll over issue I mentioned before is still giving me just a gray square roll over state. I don't know what (if anything) is supposed to show on roll over. What do you see when you roll over any of those buttons?
Also you might want to update Directx. I know it has nothing to do with
opengl but some posters in the past have reported that some things got
better.
I currently have version
When I tried to update at http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=2da43d38-db71-4c1b -bc6a-9b6652cd92a3, and install, I would get this error Even though I meet the requirements for this update, something is not letting me. I even made sure my Cryptographic Services was enabled and started. When opening PS, there were times I would get an error something to the effect that PS had a problem with the display driver so something or another was disabled (which I'm thinking it was just not allowing open GL drawing (which was usually around the time I would notice that menu bar section I posted about previously).
Also sometimes newer video card drivers are not the best drivers for a
given application. Have you went back to a set of older drivers to see
if that may cure the problem?
I've rolled back my graphics driver. Will have to wait and see if that solved anything.
As for
the ruler problem some people, from what I have read, have the same or
simular issue. There is a recent thread about 2 or 3 days ago that had
a ruler problem and I don't think it was fixed.
The recent thread was probably mine. I didn't mean to double post about that topic, but sometimes when just one person responds (and usually doesn't have anything helpful to say), others will just pass up that post. This issue is maddening, so maybe one day it will fix itself or I will move on.
Thanks for your time, I will post back if anything else goes wrong - I mean "when" something else goes wrong.

Help Required - Upload Multiple Documents functionality sometimes disappears in SharePoint 2010

Hi All,
We have a web application created in SharePoint 2010 & there we were facing an issue of not able to Upload multiple documents. After doing search on google, we have found that
pre-requisites for this functionality to be working properly are as follows:
Client Integration needs to be enabled for the web application.
The STSUpld.UploadCtl IE add-in must be enabled. (located in C:\Program Files (x86)\Microsoft Office\Office12)
The 32 bit version of Internet Explorer. The 64 bit version does not support it and neither do other, non IE, browsers.
Office 2003 or newer on the client.
After meeting all the above requirements, We are now able to see the Upload Multiple Documents link but we are failing in below 2 scenarios:
On some machines it is working fine & on some it is not.
On some machines, this option is available for sometime & sometimes it disappears.
If any one of you have experienced the same problem, then please help us with your valuable suggestions & possible solution for it.

Hi Manish,
We've just been experiencing your initial issue with Office 2007 clients not being able to use the multi-file upload functionality. Sure enough....turning on presence information in Central Admin fixes the issue. The strange thing is though that
when presence is turned off, Office 2003 and 2010 clients still work fine and it's only 2007 clients that fail. Also this issue appeared to only exist for us inside applications that have been upgraded from MOSS2007 to SP2010. Any new applications
of even new site collections within an upgraded application worked fine across all 3 Office versions.
Coincidently, we're also experiencing the more recent issue you've come across with files not uploading after clicking OK in the ActiveX. Nothing happens. Office 2010 clients work fine but 2003 and 2007 clients just don't upload the selected
files. We've found a workaround which "fixes" the issue but brings it's own set of problems so it's not ideal. Here's what we've done...
1. Open IIS, and navigate to the web where you want to use multi-file upload
2. Select Handler Mappings and Add Script Map
3. Set Request Path - shtml.dll
4. Set Executable - C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\SHTML.dll
5. Set the name to something meaningful - Multi File Upload
6. Leave the Request Restrictions as default
This should fix the issue with files not uploading but unfortunately it also prevents SharePoint Designer from accessing the site. For the application where we desperately need multi-file upload we can manage without SPD access so it's not the end
of the world but not ideal. We've actually got an outstanding incident logged with Microsoft to resolve this issue but they've yet to find a solution for us. We suggested to MS that we update authentication to Kerberos from NTLM and retry as we
seem to be getting 401 errors in the call stack so thought that could be related. We've not yet configured Kerberos so I'm not sure whether this is a solution or not.
One other point worth mentioning is that SharePoint Designer 2010 (which is free) installs the latest version (14) of the Upload ActiveX and with this installed the uploads work as expected. Also if you have Silverlight and SPD2010 installed then you
get a Silverlight control to do the upload which also works fine. Again, not ideal as rolling out SPD 2010 to affected clients isn't really a suitable solution.
Sorry I can't be any more help. Hopefully my findings might point you in the right direction. If you do find a solution (other than the IIS handler mapping) then please re-post here,
Good luck,
Ben

Components sometimes shifted

i made a swing application with about 15 components. SOMETIMES, about half the components are shifted uniformly to the upper left direction, but sometimes not. i have no idea why.
this may not be relevant, but my program first displays a login, allowing the user to login first and then enter the menu. so, in the beginning the login components are visible and the main menu components are not, and vice versa.
also, i made it using some graphical program, so the code is rather messy. it's something like this:
public void layoutContainer(Container parent) {
Insets insets = parent.getInsets();
Component c;
c = parent.getComponent(0);
if (c.isVisible()) {c.setBounds(insets.left+6,insets.top+166,538,237);}
c = parent.getComponent(1);
if (c.isVisible()) {c.setBounds(insets.left+64,insets.top+410,70,26);}
c = parent.getComponent(2);
if (c.isVisible()) {c.setBounds(insets.left+6,insets.top+410,51,26);}
c = parent.getComponent(3);
if (c.isVisible()) {c.setBounds(insets.left+141,insets.top+410,70,26);}
c = parent.getComponent(4);
if (c.isVisible()) {c.setBounds(insets.left+6,insets.top+26,538,102);}
c = parent.getComponent(5);
if (c.isVisible()) {c.setBounds(insets.left+467,insets.top+410,77,26);}
c = parent.getComponent(6);
if (c.isVisible()) {c.setBounds(insets.left+6,insets.top+6,538,19);}
c = parent.getComponent(7);
if (c.isVisible()) {c.setBounds(insets.left+416,insets.top+410,51,26);}
c = parent.getComponent(8);
if (c.isVisible()) {c.setBounds(insets.left+6,insets.top+128,538,38);}
c = parent.getComponent(9);
if (c.isVisible()) {c.setBounds(insets.left+218,insets.top+410,83,26);}
c = parent.getComponent(10);
if (c.isVisible()) {c.setBounds(insets.left+186,insets.top+211,128,19);}
c = parent.getComponent(11);
if (c.isVisible()) {c.setBounds(insets.left+186,insets.top+237,128,19);}
c = parent.getComponent(12);
if (c.isVisible()) {c.setBounds(insets.left+115,insets.top+211,70,19);}
c = parent.getComponent(13);
if (c.isVisible()) {c.setBounds(insets.left+115,insets.top+237,70,19);}
c = parent.getComponent(14);

Email attachments sometimes disappear when sending to a PC user

When I send an email with an attachment (normally a PDF or JPG), in of course an exceptable size, to a PC user, the attachment will disappear for them. When they receive and open the email, only a small gray outlined box appears for them, with an "X" through it. This does not always happen for me, only for certain PC users. I have a feeling ti may be a setting error on their end, but I need to make sure. I would love to have a fix for the issue or else a solution to tell the client to try. Thanks.

Oh man! So they say "We know this is a bug and we can't fix it since Tiger" ????? This is Apple with an army of developers and they can't fix this annoying issue???? WHAT???? I think this is a not a day more problem to fix and their professional OS X Server is affected by this problem as well and they don't fix it... their own software... what a customer care!!!
Anyway it sounds ******** and the solution is the same category... if you have only one mail in the mailbox and move to an other on a certain type of server it's getting corrupted, but the rebuild process works and when you move back it will be corrupted again! They should fix this but it looks like they will never fix it... it's a shame from a big company which sells premium products.
So if you still in contact with an Apple technician and they're opened I can provide both of the server platform when the problem can be proofed. (one where the sync is ok and one where it isn't and only with one mail in it ) Please contact me and I can help!
You can try other mail softwares and they can handle the imap protocol without major problems. I tried the following ones:
- Postbox
- Thunderbird
- Sparrow
- Mail Mate
Both works very wall but any of them is so integrated as the mail app with osx. Unfortunately if you live in the apple ecosystem and own more than one mac computer you will stuck with the apple one with all of its bugs.
...since Tiger... I can't get over it...
Sorry guys I getting angry when I hear this kind of stories...

Scroll indicator sometimes disappears in Safari iOS 8.3 bug. (On scrollable divs using "-webkit-overflow-scrolling:touch")

Hi,
After updating to iOS 8.3 on an iPad Air, it seems something is wrong with the scroll indicator on scrollable divs in Safari.
It scrolls like it should be, but randomly I just don't get to see the scroll indicator on the right side of the scrollable div.
You can see the problem when refreshing the page, sometimes the scroll indicator is visible and sometimes it is not.
Here is a small example, to view on an iPad/Safari: http://www.roidesrois.be/new_site/div_scroll.html
The code used should be correct. Before the update I never saw this problem before.
Here is an example from somebody else. http://www.quirksmode.org/css/css2/overflowscrolling.html
I see the exact same problem there too.
When using Chrome or Mercury on an iPad I don't see this problem, only in Safari.
Can someone please confirm this problem or maybe has a solution for this?
Is this a bug in Safari that needs to be solved?
Thnx in advance,
Kind regards.
Lester.

Hello to both of you.
Don't know if this will clarify or mudle the issue but in the same platform context I have a similar issue. Don't know if you are familiar with the LaPresse App (go to AppStore and download it: it is free) but it has vertical text that begins mostly offscreen (just a small portion is visible), which you can swipe upwards and eventually beyond the top, without the tablet page height ever resizing at any moment. It behaves very similarly to an Adobe Premiere title starting off-screen at the bottom, then rolling upwards (e.g. as you would swipe, on the table), and ending off-screen over the top. That's what I'm trying to reproduce using Muse and cannot achieve. As soon as I move the text below the defined page size, Muse automatically expands that page size to accomodate the new text position. I thought of turning off vertical scrolling in the Page properties to force a static page height but the scrolling options in Tablet layout are disabled (by the way: why is that?)

Audio Components Mix disappear after update to 10.1 – rescue my work?

Dear community,
after updating on 10.1 we are missing an essential feature.
Hundreds of episodes have an audiomix within the three stereo audio components (expand audio components)
audio1 = main voice, commentary (stereo)
audio2 = foley / SFX / etc. (stereo)
audio3 = music score (stereo)
On every single audio component we put audio filters and changed volume control with keyframes.
The result is a complex audio mix within a clearly arranged environment. It was very simple to understand.
Yesterday, we updated one of the episodes and noticed that our audio adjustments were not there anymore. No audio mix at all. Disaster.
For Apple developers it must be an ease to fix this issue. Maybe they just forgot that.
Please do not let mix all episodes again maybe someone has an idea?
My plan is:
A. Export the final audio mix of every episode (not editable anymore but rescued for eternity) in one stereo file
B. Export audio compoents into tree seperate stereo files wihout adjustments (if changes must be done in future)
C. Export as Roles - does anybody have experiences woking with them?
Sincerely
Violet

I'm having the same problem, When I import video from my CF cards on my newer iMac 10.8.5 OS the audio cannot be split into two mono tracks that can be ajusted seporatly. This is essential for me since all my events I film, one side is the open mic audio and the other comes from the sound system. On my old Mac with 10.7.5 I'm able to import the media then open in timeline and adjust the two audio channels seporatly. Please Help us, I need to use my much faster computer to produce on site videos.

All firefox components have disappeared. Has anyone seen this issue or have a solution?

Since last few days, my firefox browser does not display any components like address bar, buttons, even the area where the webpage is displayed. I think there was a firefox update that took place before this happened but I am not sure.
What have I tried so far :
1) uninstalled and installed firefox : got the latest firefox stub installer and installed. The issue is still there.
2) Tried to get the installer : tried to get the installer (not the stub that fetches file online during installation). Maybe I got an older one Firefox Setup 3.6.8.exe. this was working fine. I made it update itself using help menu. It updated a few time and was fine. But the last time it updated, it again started showing me the blank window.
What do I run : Windows 7, 32 bit, 4gb ram. i3 processor
Screenshot : trying to attach it.
Till then the description of what I see : the windows frame that is translucent is present and the area where the page is displayed is black. No buttons or address bar or anything. close, min, max button is present. if I hit ctrl b, the bookmark area is taken up by the translucent windows frame but nothing is displayed.

hello, other users with this problem all had an embedded intel hd3000 graphics card with an old driver present. in case this also applies to you, here would be a link to update the driver, which in turn should also address the black firefox problem: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23763 (for win7 32 bit)
in case this doesn't solve the issue or does not apply to your system, start firefox into safemode '''by pressing the shift key while the application is launching''' & disable hardware acceleration in the firefox ''menu ≡ > options > advanced > general'' (that setting will take a restart of the browser to take effect).
