Problem with "Keybord and Mouse" on Preference Pane
I can't open "Keybord and Mouse" on Preference Pane.
When I click on it, it doesn't open, just keeps loading until I click any other option except "Keybord and Mouse". Otherwise it opens an empty preference pane window, displaying nothing but the gray background.
I can't access any keybord or mouse configuration. How do I fix it?
Hi, did anyone fix this problem yet?
My problem is that i copied the 10.5.2 HD from my old Macbook to my new MBP (with the new multitouch trackpad) to save time and to avoid a new install. Everything works except the mouse and keyboad preference pane. It seems that the demos for the swipe etc are non existent, and therefore the UI does not seem to work. This seems to make sense, as the Macbook did not have the options for multitouch. Does anyone know how to fix this? Is there any way I can reinstall the missing components to avoid a fresh install?
Thanks alot for help. You can save my time
Cheers, André

870A Fuzion Power has problem with keyboard and mouse movement only in games.
Hey guys,
recently built a new system and chose to go with the 870A Fuzion Power mainboard, everything has gone very smoothly execpt for one problem, only when I play games like Crysis 2 ect the mouse seems to jolt around now and again and the keyboard decides to stop responding if I hold down the movement keys, and this is only in game not surfing the web for example. Now, I am using a wireless mouse and keyboard but I plugged in a PS/2 keyboard and the exact same thing happened. I've installed all of the drivers that came with this board and the drivers for the mouse and keyboard. Any of you guys ever had this sort of problem or know how to fix this?
Thanks.I bought a new Macbook pro in june 2010, I didn't have any keyboard or mouse issues prior to upgrading to 10.6.4 supposedly this update was made to fix some issues with keyboard and mouse becoming unresponsive. For me the opposite happened. after the upgrade, my keyboard and mouse (trackpad) becomes sometimes partially unresponsive or totally unresponsive. the only way to solve the problem is by completely turning of the computer and turning back on.. granted it doesn't happen very often.. generally once every about 2-3 weeks but it is still annoying though..
I didn't have a chance to use the computer too much on the previous version (10.6.3) so I don't know if it is software related or hardware related.. any thoughts?

Problem with keyboard and mouse pm8m-v
I have gotten this pm8m-v from a freind who knew nothing about computers. He had problems with the keyboard and mouse not responding at start up or just freeze on him. So I check it out, called MSI and even sent it to them, they claimed that there was nothing wrong with the board. So here are the specs of the computer now:
pm8m-v motherboard
2-256MB memory PC-2700 DDR 333Mhz
intel P4 2.6GHz
codegen power supply 300W
gateway CDW
western digital 40 harddrive
the rest is on board stuff
the problem is still there and it is driving me crazy, can you please help?I had the same problem with the PM8M-V, today as a matter of fact, and I kept getting locked up at the point where I had to hit enter to load the WinXP CD to setup the system. After finding this topic I tried a different keyboard. The one that was being used was a Kennsiington PS2 cheapo, I swapped it for a Microsoft (one of those ergonomic styles and I've had it for a long time) Keyboard PS2, and the problem went away. I'm typing on the Kennsington right now, so it's fine just wasn't liked by the PM8M-V for some reason.

Strange problem with RDP and mouse, only solved after minimize/maximize
Good day,
We have this very annoying problem with a RDP Terminal Server. It is Windows Server 2008 R2 SP1.
This server has the Session Host role installed, with local RDP user licenses.
We only have this issue when running a certain application.
This application is called Rockwell FactoryTalk View and this in an application to display industrial processes.
It will take the Full Screen in a fixed resolution and will display buttons, objects, values... The application also uses Internet Explorer cache so I think it uses ActiveX, Flash or Java, I don't know.
What sometimes happens is this:
- The mouse point is able to move in the entire screen (good)
- The mouse button will only work in 1 certain area of the screen (which is a small rectangle)
- The mouse "hovering" above objects will also only highlight items that are in this rectangle
- The keyboard remains functional and with alt-tab other objects or other applications can get focus, but still no mouse clicking
The problem can be solved by:
- Minimizing the RDP window and maximizing it again
- Or: Sending a message to the session using task manager, after clicking "OK" on that message the problem is gone
Normally, about 5 users will have this application opened in their session, the "crash" is only effecting 1 session.
The problem seems to happen randomly and we don't know if we should point to the FactoryTalk application, or to Terminal Services/RDP. The end users have no rights to minimize/maximize, this is not the solution.
Is it possible to have any input on this please?
Thank you.Hi,
Thank you for posting in Windows Server Forum.
Firstly please check with the application support team whether the application is fully supported by Windows Server 2008 R2 in remote session. In addition, suggest you to update the client RDP version to RDP 8.1 and check the result for better feature and functionality.
Apart from this, there is Hotfix for the issue. Please download, install and check the result.
Cause:
The issue occurs because the remote desktop ActiveX object does not deactivate the focus of the remote desktop session when the focus is lost. Because the focus is still activated, the remote desktop ActiveX object cannot set the focus of the remote desktop
session again when you change the focus back to the session.
A remote desktop session does not respond to keyboard input or mouse input after it loses the focus in Windows 7 or in Windows Server 2008 R2

Hope it helps!

Problem with JScrollPane and Mouse Event in JDK 1.4
The folowing code works fine with JDK 1.3. But not with JDK 1.4. It has got a JPanel(main panel) which hosts JScrollPane which hosts another JPanel (drawing Panel). If I remove(do not add) JScrollPane to the main Panel and ad drawing panel directly to the main panel, it works.
Thanks.
In order to replicate the exact scenario, I have modified Sun's tutorial ScrollDemo2.java
* This code is based on an example provided by John Vella,
* a tutorial reader.

Thanks for the suggestionI've got it... I know that inside the paitComponet method you can't call setSize() in jdk1.4, but you could in previous versions... that has caused al lot of problems to me...

Whenever I am using Time Machine to backup to my Time Capsule my external mouse becomes unreliable, this happens with both my logitech USB mouse and my bluetooth magic mouse. This did not happen when I was using an external drive connected to firewire for my backups. Additionally the trackpad on the laptop works fine.
Any ideas?My problem is almost the same:
Using Time Capsule (MC343) with USB connected wireless mouse on Snow Leopard, MB-Pro - when Time Machine starts to write backup mouse cursor jumps around the screen, like movement reading is delayed by something.
When I use my external hard-drive connected via USB for backups this problem doesn't occur. -
Problem with LiveDock and Mouse Pad
Hi,
I write from Spain. When I use mouse pad with Livedock with my Xperia Arc S, both mousebuttons open apps. Before, with Android 2.3.4, left one was accept and right one was go back.
Will Sony solucionate this problem?
In other order, I can´t use usb masive storage with Livedock. How I have to connect it? Where can I see files of the usb in my Arc S?
My Android version is 4.0.4.
Thanks.I’ll start with this question, what format is the external storage you are connecting to?

Problem with TrayIcon and mouse events
Hi,
I am trying to listen for a mouseEntered event on a TrayIcon.
This is the code i am using:
final TrayIcon icon = new TrayIcon(getImage(), "tray icon");
final SystemTray tray = SystemTray.getSystemTray();
try {
tray.add(icon);
}catch (AWTException e) {System.out.println("TrayIcon could not be added.");return;}
icon.addMouseListener(new MouseAdapter() {
@Override
public void mouseEntered(MouseEvent e){
System.out.println("works");
}});The icon is correctly shown in the tray bar, but the mouse entered event is not working.
I have to say that i am using the exactly same code to achieve the same effect on a JButton and it works without any problem.
Is there anything wrong?
Thanks,
Niteis there a way to request my thread to be moved into Swing section? Well, the idea is to post the question in the proper forum in the first place.
yes, but i didnt find anything related to my problem.Really, I found posted examples of using a MouseListener.
Does your code work for other events or is the problem only related to mouseEntered() events (which may not be supported, I don't know since I don't have the proper API to use TrayIcons)?
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Then maybe others can test your code or see something else wrong. -
my kids computer began acting up this spring...so I shut it down.
Would not stay turned off, various noises almost continually, jumping highlights, etc.
Decided to reinstall os x snow leopard. insert disc and icon appears. then 3 icons with x in a column.
automatically highlights middle icon and will not allow me to select one above. Says install xcode.
not what i want to do.
any help?What model iMac do you have?
What version of Mac OS is it running? If you don't know, try to give approximations on when it was set up and whether it was ever updated so we can take our best guess.
How are you trying to boot from the install disc? Your description of 3 icons with x in a column' leads me to believe that you aren't booting from the install disc, but rather you are inserting the disc after booting from the OS that is installed on the hard drive. If that is what is happening you'll see something like this, although it will vary depending on the actual version of the Install Disc that you have and how you've chosen to view the files (icon, list, column, etc).
What happens if you restart the system with the Install Disc inserted, then quickly hold down the 'c' key so that the system attempts to boot from the Install Disc. Do you still experience the same issue? -
Hi,
I'm running OS 10.11 and am having some consistent problems with Mail and Safari on my MacPro Dual 2.66. Here they are:
Sometimes, for no apparent reason, selecting these applications from the dock no longer opens the application (or a new window if already opened), but causes them to be revealed in the finder.
In Safari, when this problem occurs, another symptom seems to be that new windows will ONLY open in a new tab, even though I have preferences set to open links in a new window. If I click on a bookmark within a folder in the bookmark toolbar, Safari will open ALL the bookmarks in the folder in new tabs!!
In Mail, when I open my Inbox, clicking on various messages will highlight (in blue) ALL the messages I'm clicking on, instead of simply displaying the highlighted message in the reader.
The only way to get things back to normal is to reboot my machine, which is getting to be a total drag, especially since this seems to happen fairly often.
One other thing that may be related- if my screen saver is running, and I move the mouse to go to an active screen, the computer will "freeze." It stays like this indefinitely- I figured out that if I press the button on the machine itself it will go to sleep, and I can wake it up and then everything is fine, but I don't understand what's going on.
I have tried using Disk Utility and Disk Warrior, and have used OnyX to clean out my system cache and aall sorts of other stuff, but to no avail.
Is anybody else experiencing any of this? I'm starting to get really frustrated. Thanks for any advice.
Cheers,
AndrewScott,
I had posted earlier that I had Flash payer problems and then QuickTime and PDF preview problems too, on my Intel PowerMac. I could not figure out what the problem was, because fixing permissions and moving plugins did not work. Console indicated that the Quicktime components were not found, with the problem in a webkit pref file somewhere (nil field value). Anyway, I bailed and reinstalled Leopard from a 10.5.0 DVD, and then updated using the combo updater to 10.5.3. Everything worked. Then, after the 'Java for Mac OSX 10.5 Update 1', it all broke again. This time, repairing permissions resulted in:
User differs on "System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Home/lib/jvm.cfg", should be 0, user is 95.
User differs on "System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Libraries/classlist" , should be 0, user is 95.
Now it all works again. This is obviously a flaw with the Java update, and also somehow Disk Utility did not find it earlier. Anyway, take a look at reverting the Java update, or manually changing user for those files (I suppose user 0 is root, but maybe it is nobody).
Obscure.... -
Problem with JFrame and busy/wait Cursor
Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread. -
Problems with Safari and Firefox (HTTP?)
Problems with Safari and Firefox (HTTP?)
On a laptop G4, 10.5.8 and Safari 5.02 I experience the following:
On the account of my oldest daughter everything works fine, i.e. wireless internet works and no problems with mail or safari.
On the same laptop, on the account of my other daughter, the wireless is OK, she can mail etc. But safari nor firefox works. It says: can’t find server (whatever site) and in the activity window it looks if safari tries to open files (in the safari preferences-folder) in stead of http. Same applies to Firefox, so maybe it has more to do with HTTP in general?
What goes wrong? What to do? I tried the following on the host terminal (tips from Apple)
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
and
defaults delete com.apple.safari WebKitDNSPrefetchingEnabled
but that did not help,
NanneI'm still wondering why it happens now at this moment in time...
PC does seem to be a bit odd & inconsistent, the few times I've tested with it, at least so far as we content filtering goes; and if I remember rightly, you're not the first to report previously ok settings suddenly preventing some or all internet until pc is switched off altogether.
It may work when re-enabled -
Problem with yosemite and parallels
Since I have upgraded to yosemite and parallels 10 my windows 7 has been using a lot of CPU resources. Windows 7 runs very slow and it been using almost constantly 100% of one of the quads resources. This just started to happen when I upgraded, because I did not have this problem with Mavericks and Parallels 9 or 10. I have an iMac 2011, 8GB of Ram. Has anybody had this issue. Thanks.
Thanks for the response. I was searching on a parallels forum website and found the following:
As from the symptoms, the issue can lie in NVRAM preferences of your particular Mac.
Please do the following to solve:
open Terminal application on Mac (Applications/Terminal.app)
please type this command (you may copy-paste it to the terminal from this message):
sudo nvram boot-args="debug=0xd4e"
Hit Enter.
You will be prompted to enter Mac user password. Please type it and hit Enter.
Note: you won't see what you are typing, just type and hit Enter. If you don't have Mac user password, please create a temporary one.
Then you may restart your Mac and the issue should be solved.
If not - please reply me here and I'll create a ticket for you in Support.
I did the above and it seemed to correct the problem. -

it was working fine until yesterday, i've been searching about xcb_io.c but sadly i haven't found anything useful.
Edit:
it seems i can run it fine as sudo but not as a regular user

well it seems that there was something wrong with my .zsnes folder, i deleted it (well first i made a backup of it) and i can run zsnes again.
Edit3:
well, it seems i got a problem with opengl and my catalyst driver (but i'm guessing because i haven't tried with radeon) because i can use it without opengl but as soon as i change the video option to use opengl it crashes with the same error (zsnes: xcb_io.c:515: _XReply: Assertion `!dpy->xcb->reply_data' failed.) should i file a bug report or something???

Problems with SwingWorker and classes in my new job, ;), can you help me?
Hi all, ;)
First of all, sorry about my poor English.
I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
I have two classes:
Form1: Its a JPanel class with JProgressBar and JLabel inside.
FormularioApplet: (the main) Its a JPanel class with a form1 inside.
I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
In Form1 I make a Thread that update the progress bar and gets the fole from the server.
In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
THE PROBLEM:
The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
I put in bold the important lines.
Note: My level of JAVA, you can see, is not elevated.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
