JOptionPane.showMessageDialog blinks first at upper left corner

Hello everybody,
I am facing the following problem using SWING 1.1.1 (sorry but I need to use this old guy): When I invoke a dialog by using JOptionPane.showMessageDialog the dialog first blinks at the upper left corner of the parent window and after it appears correctly at the center.
This happens very quickly, but it is really annoying ! Can someone help me ?
Thanks in advance.

it's rather bad because old version swing is used very rarely now. and I do not see
this bug in later version swing.

Ghosting T60 - blinking cursor in upper left

Hello,
I am trying to ghost my T60 so that I can install a larger HDD. The ghost itself is working - I can see the data when the drive is connected to another PC, but when I install in the laptop and try to boot, it goes through the POST then just sits there with a blinking cursor in the upper left corner? I have googled and seen a few hits on this, but no real solution. Anyone have any ideas or know the solution?
Using ghost32.exe version 8.0. I have tried using the -IB extension and also writing the new ghost image both in the T60 and also on a separate PC, with the same results.
Thanks!

I read another post - see below. Any thoughts on this? I am attempting a mere clone of the drives using acronis.
Thanks..
Quoted from another post....
When I clone my HD (using Apricorn Software), I have to:
1. Go into BIOS first and set Pre-Desktop Security to "Disabled".
2. Mount the Source drive in the External USB Enclosure.
3. Mount the Destination Drive in the Thinkpad.
4. If I don't do this, the Cloned drive is NOT bootable (just a blinking cursor).

Illustrator CS 6 won't paste into a text box/paragraph of text, instead pastes a new line of text in the upper left corner of my document. How can I get it to paste into the selected paragraph or highlighted text like normal?

I've done it a million times, I copy a selection of type...I select the type that I want to replace it with, and then I paste. Now, Illustrator will only paste the text as a "point text" (a single line) somewhere else on the artboard—it seems to always be the upper left corner of the art board.

peg,
In cases of sudden appearance of strangenesses, the list may be relevant, hopefully the easy part at the top.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

Iframe flash bug (redrawing the iframe in upper left corner)??

Hi All.
Has anyone found a fix for this safari bug. When I place an iframe on my web page holding a flash file it looks fine on all other browsers than safari!!
In safari (latest version, not beta and earlier versions) the first time a visitor opens the page the flash movie is drawn in the upper left corner as well as the position it should be in. If the visitor reloads the page it looks ok and the "extra" flash movie is no longer in the upper left corner.
You can see the site here: www.trierski.dk
Any advice would be great..

Haven't tested with Safari on PC. The problem I want to solve is with the Mac version of Safari... Version 2.0.4 (419.3) Not the beta versions...

Problem with windows shrinking vertically and becoming stuck in upper-left corner of screen.

Does anyone else have problems with open windows shrinking vertically and becoming "pinned" to the top-left corner of the screen in OSX 10.9? They snap back to the upper-left if I try to move them. I have to Quit or Force Quit the apps and restart them.
I have a Mac Mini, and I have it hooked up to a TV via HDMI. This only seems to happen when I switch the TV input source *from* the Mac Mini to, for example, DirecTV. When I switch the TV's input source *back* to the Mac Mini HDMI connection, all seems fine; except that some or all of the windows that were on the desktop have shrunken vertically, and they are "stuck" in the upper-left corner of the screen. When I try to move the windows out of the upper-left corner, they snap right back. Very weird.
Everything else about the desktop and the Mac Mini appears just as I left it. The screen resolution hasn't changed - nothing like that. Although my first thought is perhaps the screen resolution is, briefly, changed to a lower resolution when the Mac Mini detects that its "monitor" connected via HDMI (in this case my TV) doesn't appear to be there because I have switched the input source of the TV. That's just a guess. And even if that's correct, I don't know how to fix it.
Any help would be greatly appreciated.
BTW, I don't remember this happening before I upgraded to OSX 10.9 Mavericks. I'm not 100%, but it seems like something I would have remembered. So the culprit could be 10.9, or it could be something else I have installed recently.
Thank you to anyone that can answer this for me.

same here:
Overview: I've seen it occur with the symptoms described by the OP while running Xcode, almost exclusively after waking my laptop from sleep mode. It effects non-Apple apps as well, but sometimes differently-- the window(s) open in Eclipse Juno for instance will sometimes disappear entirely such that they are totally inaccessible. As the OP noted the only way to clear the problem is to force quit the app and restart it (quite a hassle if you have multiple project windows open at once). I run Juno on Win32 and debian Linux also and have never seen behavior like this, so given that the problem has been observed in Apple branded apps and the fact that it only started after I installed Mavericks I would also posit that it is a Mavericks bug. That said, I do run a third-party app called WindowMagnet (v. 1.6 by CrowdCafe) that affects the window system, allowing Windows 7 Aero style window snapping; does anyone else having this problem use WindowMagnet?
Steps to reproduce: open Xcode, put the machine to sleep, wake the machine -- this bug will appear intermittently
Expected results: windows should remain the same size/configuration they held prior to sleep
Actual results: intermittently windows will be 'stuck' in the upper-left corner of the display or entirely invisible

I have an iPad2 and I can't delete some apps I downloaded that I don't want. I can get the apps lto wiggle, but there is no X in the upper left corner for deletion. Any help is much appreciated.

I have an iPad2 and I can't delete some apps I was downloading but froze. I can get the apps to wiggle, but there is no X in the upper left corner for deletion. I have tried re-setting and didn't work. Help will be appreciated.

See if anything here helps.
If the downloads are stalled or "waiting" - try these suggestions.
Tap the "waiting" icon and see if you can pause it. If it does pause, then tap it again and see if it will resume. If that works, repeat the same steps for each "waiting" icon.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>iTunes & App Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>iTunes & App Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered.
If all else fails, download the updates or the apps in iTunes on your computer and then sync the content to your iPad.

White Screen with "1, unknown word_" in upper left corner

I was attempting to reinstall system software (original was 8.1, upgraded to 9, and then 10) to this old computer so that I could give it away without giving away my personal info -- it seemed no matter what, it kept asking me for my password on restart.
God knows what I did next (because I tried EVERYTHING!) but now all I get is a white screen with "1, unknown word_" showing up teeny in the upper left corner of the screen.
Real problem is, I can't get it to start up from any of my old system CDs -- I'm thinking that maybe it's not recognizing my USB port for the keyboard? (installed in one of the PCI slots -- not original hardware).
USB keyboard always worked fine BEFORE I tried to re-install software. Unfortunately, I burnt out my old ADB keyboard so that's an unavailable alternative....
Any suggestions on how to get it up & running? I would just as well trash it, but there's a nonprofit I know that could actually use it...
PowerMac G3 Beige Desktop Mac OS X (10.0.x) 233 mhz, pathetically small 4g hard drive
PowerMac G3 Beige Desktop Mac OS X (10.0.x) 233 mhz, pathetically small 4G hard drive

Can you borrow an ADB keyboard to see if you can reboot from the CD. Is there a Macintosh User Group in your area or any other Mac users you know at work, etc. that might have a spare one around?
If you can't temporarily borrow one, you might consider buying one:
eBay search for ADB Keyboard
I'm sure there are other Mac stores where you could find a ADB keyboard, check for ads in the back of your favorite Mac magazine.
Now, when you did the OS installations/upgrades, did you select an option that preserves the existing User accounts rather than a clean installation? I don't know why else you would get prompted for your password unless that was the case. One option to completely erase the disk before the OS install is to run Disk Utility, it's usually available from the Menu Bar when the installer first starts. If you truly want to wipe the HD clean of any info, select the Zero All Data option, which might take a while for a 4GB drive.

Cursor moves to upper left corner when not in use

Hi,
Since I installed 10.9.3 (last night) the cursor has been jumping to the upper left corner when it is not in use for more than about 3 to 5 seconds. I'm using a bluetooth mouse and keyboard.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Screen showing a whitening of the screen on the upper left corner

I have a screen problem with my 1G iPhone (non-3G). I bought it within a week of introduction and in about a year, there was noticeable whitening of the upper left corner. I took it to a Apple store, they replaced it with another phone which has a speaker issue and so they replaced that second with another phone (right about when 3G was released). Now, the new phone is showing similar whitening on the upper left corner. Plus I see two bubbles in the display (about the size of a degree symbol) right in the upper left corner. I don't have Apple care coverage anymore. My wife's iPhone does not show this problem (though hers was also replaced for another reason within a year). We have had good luck with Apple products (7 laptops, 2 iMacs over 6 years or so) but we are leery of upgrading to 3G if there is so much trouble. Is it the first generation issue or folks also see this in the 3G model? Any help is appreciated. (The phone was never dropped and I take good care of it)

I haven't read anything about a recall, so if you have a first generation iPhone that is no longer under warranty and you didn't purchase the AppleCare extended warranty, Apple probably won't do anything for you - at least not for free. Apple doesn't offer a menu of repair services for the iPhone. Apple offers an out of warranty or not covered under the warranty repair price, which pays for an exchange. You can call AppleCare at (800) 694-7466, or make an appointment at an Apple store if there is one nearby.
Or do a Google search with iPhone repair, or iPhone out of warranty repair. Depending on what needs to be repaired or replaced, the cost for 3rd party repair services may not be a whole lot less than Apple's repair price, which pays for an exchange and will include a warranty.

How do I get rid of yahoo toolbar and get back my orange firefox button in the upper left corner of screen so I can use my stuff again?

Yahoo toolbar suddenly imposed itself as my log on screen whenever I booted up my computer and clicked on Firefox. Now I can't get to my bookmarks even though it told me that if I activated the new bookmark system it would transfer my old ones. It didn't happen. The toolbar has no bar for typing in a www.http address. I cannot use it and don't want it. I am using Explorer just so I can access my bookmark address, but don't like Explorer. I want my old Firefox screen back that has the little orange button in the upper left corner of the screen. How can I get there? My computer use has been highly curtailed by this unrequested invasion!

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).<br />
If you are in full screen mode then hover the mouse to the top to make the Navigation Toolbar and Tab bar appear.<br />
You can click the Maximize button at the top right to leave full screen mode or right click empty space on a toolbar and use "Exit Full Screen Mode" or press F11.<br />
If the menu bar is hidden then press the F10 key or hold down the Alt key to make the menu bar appear.
*https://support.mozilla.com/kb/Menu+bar+is+missing
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
*Open the Customize window via "View > Toolbars > Customize"
*Check that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
*If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette in the customize window to the Bookmarks Toolbar
*If missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
*If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up

I have these black boxes surrounding things, e.g., there is a black box around the red "close" button on the upper left corner of this page. There is also an oblong black box

Hi - I'm not only having trouble waking up my MBP from sleep and having to restart repeatedly which is a pain in itself, but now when it restarted, I have these black boxes surrounding things, e.g., there is a black box around the red "close" button on the upper left corner of this page. There is also an oblong resizable black box sitting on top of anything. The content changes depending on the actions I take. Right now it says, "You are currently on a close button. To click this button, which closes the current window, press Control-Option-Space." Right now I'm open in Firefox, but it doesn't matter if only Finder is open, it's still there. I've tried closing all my applications and restarting and I also reset the PRAM. It won't go away. It's probably something simple, but I don't know how to get rid of it. Any suggestions are welcome.
Thanks,
Janet

Thanks so much. I saw this on "desktop strangeness" immediately after I posted and tried to retract my question. It worked perfectly. I'm not sure how VoiceOver got turned on unless something happened when I was trying to wake up the computer. I open the lid and it flashes whatever is open and then the screen goes black and I can't wake it up. Still looking for the resolution to this.

How to display a frame at the upper left corner of each screen?

hi,
below are 2 ways to display a frame at the upper left corner of each screen (i have 2 monitors).
both work but the 2nd way is much slower. which, if any, of the 2 approaches is "more" correct?
import java.awt.Canvas;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.DisplayMode;
import java.awt.event.MouseListener;

import java.awt.GraphicsEnvironment;
import java.awt.Point;
import java.awt.Rectangle;
import java.awt.Toolkit;
import javax.swing.JFrame;
import javax.swing.JPanel;
// the thing that matters in here is setting the frame's location: xCoord
// is incremented in each iteration by the current screen's width and
// is used to set the frame's x-coordinate.
public static void main(String args[])
      GraphicsEnvironment gEnviron = GraphicsEnvironment.getLocalGraphicsEnvironment();
      GraphicsDevice[]    gDevices = gEnviron.getScreenDevices();
      Color colors[] = {Color.blue, Color.red};
      for(int i = 0, xCoord = 0; i < gDevices.length; i++)
         // set panel's size and frame's size to take up the whole screen
         DisplayMode didsplayMode = gDevices.getDisplayMode();
int screenWidth = didsplayMode.getWidth();
int screenHeight = didsplayMode.getHeight();

frame.setLocation(xCoord, 0);
xCoord += screenWidth;
frame.addMouseListener
new MouseAdapter()
public void mousePressed(MouseEvent event) {System.exit(1);}
frame.setVisible(true);
// this is a lot slower and may not be correct: it sets the frame's location by calling
// getConfigurations() on each screen device but using only the 1st configuration
// (it returns 6 on my computer) to get the bounds (for the frame's x-coord).
// a screen device has 1 or more configuration objects but do all the objects
// of the device report the same bounds? if the anwser is yes, then the code
// is correct, but i'm not sure.
public static void main1(String args[])
GraphicsEnvironment gEnviron = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gDevices = gEnviron.getScreenDevices();
Color colors[] = {Color.blue, Color.red};

JPanel panel = new JPanel();
panel.setBackground(colors[i % colors.length]);
JFrame frame = new JFrame();
frame.setSize(new Dimension(screenWidth, screenHeight));
frame.setContentPane(panel);
frame.setUndecorated(true);
// set location of frame: getConfigurations() is very time consuming
GraphicsConfiguration[] gConfig = gDevices[i].getConfigurations();
// on my computer: gConfig.length == 6. using the 1st from each set of configs
Rectangle gConfigBounds = gConfig[0].getBounds();
frame.setLocation(gConfigBounds.x, gConfigBounds.y);
frame.addMouseListener
new MouseAdapter()
public void mousePressed(MouseEvent event) {System.exit(1);}
frame.setVisible(true);
thank you.
