Thunderbird 24.6.0 suddenly stops accepting keyboard input in the middle of typing a message

On a system running Debian Testing (kernel version 3.13.10-1), at times Thunderbird 24.6.0 suddenly stops accepting keyboard input in the middle of typing a message. Some times, it will not accept keyboard input from the time a new message window opens (both from click Write or Reply).
Regardless of when the problem starts, I can still copy text from another source and paste it into the message, and I can still send the message.
Sometimes, the problem will clear up itself after a few minutes, meaning I can suddenly start typing in the open message window, but sometimes not, and I will have to close the message window and restart Thunderbird or reboot the system.

My keyboard has gone crazy: When typing all the upper letters (q,w,e,r,t,y,u,i,o,p,å,) at the same time the number above (1,2,3,4,5,6,7,8,9,0) is also typing. Somehow I must have activated an effect whiteout knowing it. Pleas help me back to standard keyboard

Firefox and Thunderbird are suddenly not accepting keyboard input

Keyboard shortcuts still work just input in any kind of input field fails so I can still use ctrl+C / CTRL+V to somewhat use firefox and Thunderbird But all input fields are completely unresponsive to keyboard input
The problem suddenly arose while I was browsing.
I have the same issue on all program's based on the Gecko engine and I confirmed them so far in Firefox, waterfox, instantbird, thunderbird and fossamail. However chromium / windows / basically everythign n
To fix it I tried the following:
Restarting firefox
Restarting firefox in savemode
Rebooting
Changing the keyboard layout in windows
Using a different keyboard
Again rebooting
Pressing F7 to check for caret mode which was disabled
pressing winkey + F9 (Whatever that does)
I am running windows 8.1(x64)

Solved, Changing the keyboard layout again and rebooting fixed it. I tried using the on screen keyboard which worked so I changed the keyboard layout again and rebooted and now it works just fine. I still wonder what caused a Gecko wide issue like this?

My keyboard has gone crazy! Please help!

I just bought my iMac G5 earlier this month, right before the new iMacs came out. It has been working fine until two days ago. The keyboard stopped working, as in you cannot type anything, but if you click the mouse in the address bar of the safari browser or any other text area, you will see that the spacebar or random letters will write themselves over and over again. If you just happen to nudge or lift the keyboard off of the desk, the volume will sky-rocket and this annoying beeping will ensue. I went into my disc utility and verified and repaired my volumes and it did find errors and it did correct them. After that my keyboard worked again. Last night I came home and found that my iMac's keyboard was at it again and making those horrible error noises and the keyboard did not work. I want to wipe my HD with my startup disc but I cannot access that since I need the C button to initiate the process. As I said before, this is a very new machine and I have very little files on it, which have already been backed up, so it shouldn't be a memory problem. I will probably be calling the help line tonight, but any ideas would be greatly appreciated! Oh and I forgot to mention, it is not a wireless keyboard.

You still have time left on your phone tech help, so call Apple and discuss this with them. It sounds like a faulty keyboard that needs to be replaced or an internal problem, but whatever it is, let Apple sort it out for you.

Apple Wireless Keyboard Gone Crazy!

My Apple Wireless Keyboard's keys have either turned off or changed. For example, the keys QWERTYASDFGHZXCVBP123456,;'[]-=\[/ Do not work, and the others have gone crazy. They keys NMJKLIO Are displayed and/or work as:
N: 0
J: 1
K: 2
L: 3
I: 4
O:5
M:6
I am currently typing this with an USB Hewlett-Packard Keyboard, which my iMac Mid 2011 doesn't like.
Is there anyone that can tell me how to fix this, perhaps someone running Lion, so I don't have to look up the differences on how to do stuff.
Also It would be really helpful If someone posted the Microsoft Windows-OS X Keyboard keys conversions!
Thanks.

Wow, thats insane.
Firstly, go into System Preferences > Keyboard > check "Show Keyboard & Character Viewers in menu bar".
Now in the top menu bar you should see a new square icon with an asterisk in it, click and select "Show Keyboard Viewer". You can use this this graphical keyboard to input just as a regular keyboard, and also see which modifer keys correspond as you hold them down.
Now, I'm guessing whatever is wrong its probably not with OSX if you can use your HP.
But in any case you should disconnect any peripherals and restart your iMac, IF you don't have automatic login turned on I suggest you do beforehand, just in case the HP bombs out too.
Now after restart, delete your Apple wireless keyboard from Bluetooth Preferences device list, and then turn your apple keyboard off by pressing and holding the power until the green light goes off, then single press to turn back on. Now click + in the device list, or "Set Up Bluetooth Devise" from the Bluetooth menu bar icon - see if you can re-pair it and test it out.
If that doesn't work, its probably hardware and you should take it back to the Apple store.
Good luck man.

I have a new mac book pro (sept 2014) and am suddenly stuck on the log-in screen. Keyboard input is not working to enter my password. Seems to be a log in issue as keyboard works for forced troubleshooting. (And b/c when I first noticed the problem, I was able to enter my log in password but then everything sort of froze. Now, no ability to enter the password.) Already tried a basic restart and a cmmnd/ cntrl/ pwr troubleshoot to no effect.

Imac Keyboard Gone Crazy Help!!!!!

Hi,
Try new batteries.
And try re "pairing" the keyboard with your iMac.
Open System Preferences / Bluetooth
Click - to remove the mouse from the list on the left.
Now click +
That will prompt the Bluetooth Setup Assistant so you can re "pair" the keyboard. Make sure the keyboard is powered on and discoverable.

Spaces locks keyboard input

Per Sean Dale1, the following was mis-posted in the 10.5 Leopard thread (original post here: http://discussions.apple.com/thread.jspa?threadID=2201088):
Have been running into this problem more and more frequently on both a MacBook Pro and Mac Pro tower running 10.6.1 and 10.6.2: when I Control-right-arrow to move to my other "space" one or two of two bad things will happen:
(1) the icon in the middle-bottom of the screen showing which "space" I'm in does NOT fade away and disappear
(2) I am prevented from doing ANY keyboard-input into my programs there. I will be able to click and highlight windows using the mouse, as well as see menus activating and such, but anywhere there is a text field (browser or address book or ANYwhere) keyboard input is not displayed.
The only solution is to go into the Activity Monitor and quit the Dock application.
Have been seeing this problem for a few weeks which persists through reboots and such.
Ideas?

This issue is being covered in more detail at this thread:
http://discussions.apple.com/thread.jspa?threadID=2161076
This suddenly started happening to me yesterday and now happens every time I switch Spaces with the keyboard. I've found that the only way around it is to only use the menubar icon to switch. Because I'm so used to clicking keys to switch Spaces and still do it unconsciously, I've disabled the keys in Spaces prefs.

OSX/SL 10.6.8 all window apps lose keyboard input; mouse and cmd-N work for spaces

Input suddenly stops going to all applications, from MacBook Pro and wireless keyboards, and from "Show Keyboard viewer" (OSX 10.6.8 'Snow Leopard', MacBook Pro). Though the OSX Keyboard Viewer shows the keys onscreen as they are pressed on the MacBook and wireless keyboards. 'Spaces' responds to cmd-N commands, but no input is possible to any running or newly-started 3rd party or Apple-provided application. Killing off applications one by one doesn't recover keyboard input ability; a complete reboot appears necessary to restore the ability to key input into applications. This happens repeatedly, yet never registers as an OS/X 'crash' because 'Force Quit'ting applications and restarting is still possible using only the magic mouse or trackpad. No data whether only logging out and back in would correct the apparent input-focus disconnect of all applications with the window manager. There may be some way to restart the window manager by using the mouse to open up new apps and/or cut and paste characters ( including a carriage return ) or cut and paste entire saved typed commands into a terminal window.

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.
Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Photohop CS6 Update to 13.0.2 breaks keyboard input and shortcuts

Hi,
I just got the new update to 13.0.2 and after installing it Photoshop doesn't recognize keyboard input as expected? Shortcuts are not working anymore. Input values are not recognized. Text editing not possible anymore. etc.
And: When I start Photoshop I get the following trial info:
Master Collection trial. 32767 DAYS REMAINING
Thats over 89 years – I can live with that. ;-)
But there is something wrong with that update, that makes it impossible to continue my work.
Regards
PS: Is it possible to uninstall this update or do I have to uninstall Photoshop at all?

Thank you for the quick answer.
Sytem Info tells me …
Optional and third party plug-ins:
   Interpolate CS6 (13.0) ©1993-2012 Adobe Systems Incorporated - from the file “Interpolate.plugin”
   Match Edges CS6 (13.0) ©1993-2012 Adobe Systems Incorporated - from the file “Interpolate.plugin”
Plug-ins that failed to load: NONE
Flash:
   Mini Bridge
   Kuler
Installed TWAIN devices: NONE
In the meantime I did a system restart and several Photoshop restarts. Finally some weirdness is gone. Trial mode seems to be gone and Photoshop seems to be activated again.
Two thing left:
1. I do have a text element, for instance, thats acting weird. The screenshot shows two "Login" text items with exactly the same settings for font and size. But they are displayed differently.
Easy fix: delete the weirdo and create a new one. But still worth mentioning, I think.
2. One of my favorite shortcuts is gone. cmd+alt+0 (num pad) to set zoom to 100%
Easy fix: set the shortcut again via Edit > Keyboard shortcuts …
Sorry for panicking, but I was really worried to lose the day looking at installers. ;-)

Photoshop CS5 Shortcuts Gone Crazy

The CS5 shortcuts were working fine for the past 2 weeks but now have gone crazy. When I hit Shift + F6, it flips my slection horizontally when it should bring up the Select > Modify > Feather. When I hit Shift + F5, it should bring up the Edit > Fill dialog box but instead it does a Select > Modify > Grow.
I deleted the PS Prefs file but that did not work. Anyone else have this issue? Any suggestions on how to fix it?
Thanks & Regards, Murray

Zeno, no,I did not reprogram any and I checked Edit>Keyboard Shortcuts the list is as it should be - Shift+F5 still shows as Fill; Shift+F6 still shows as Feather;
Other wrong shorts:
Shift+F7 now functions as Transform>Flip Vertical
Shift+F8 now functions as Transform> Rotate 90 deg CW
Shift+F9 now functions as Transform> Rotate 90 deg CCW
None of these incorrect shortcuts shows up in the Keyboard Shortcuts table. There are no other keyboard shortcut configurations other than the PS default table.
As mentioned earlier I have has CS5 installed for 2 weeks now and used the Shift + F5 for Edit>Fill about 50 times a day. I used Shift + F6 to feather a few times as well.
Thanks and regards, Murray

IdeaCentre A310: Screen's gone crazy

I've been using my A310 for 7 months without any problems but suddenly the screen's gone crazy. The touch controls (on the bottom right hand side of the screen) don't respond to touch any more, but the on-screen menu for managing the display keeps popping up and making random changes to the screen settings. I've downloaded and installed the video driver on the Lenovo support site but it doesn't help. Any suggestions?? It's making the machine entirely unusable (not least because it occasionally chooses to switch the display off for periods of up to an hour!!).
Any help or suggestions gratefully received, before I send it back under warranty.......

hey Benj11,
try uninstalling the video drivers, let Windows install its generic drivers and update the bios.
if these does not resolve it send it to the service center

Memory gone CRAZY PLEASE help

All,
This another question regarding my app, which has a main frame that contains Tabbedpane and have desktopPane attached inside. Within desktopPane I have multiple JInternalFrame. In each internalframe a textarea is attached for taking user input and displaying server feedback (the textarea has private classes that telnet to the server to do the input and output stuff).
I was testing my app last night and found out following problems:
1.) Memory just gone crazy! I opened several internal frames and did "cat *" on each of them just to test it out. I noticed the memory just gone crazy and the app become really slow responding. after I close the internal frames speed start getting better but memory is still not being released.
2.) I use InputStream.read() to read single byte from input stream. the return is an "int", I first convert it to a "char" and then cast it to a "string" then use the JTextArea.append("string") to append it to the textarea but it displays a little square after I press enter each time.
I appreciate your time and advise, thank you.

You can allocate extra memory to a Java program by putting something like
java -Xmx256m Myclass
That should tell you if running out of memory is really your problem.
Memory from abandoned items isn't recovered until the JVM decides to do a "garbage collection" which it doesn't usually bother with until it finds memory a bit tight.
You shouldn't cast byte input to char. In Java a character is a 16 bit UNICODE code value, and it's relationship with bytes depends on the "character encoding", by default the one native to your operating system.
If you want to read character input from a file etc. then use a Reader not an InputStream. If necessary you can "wrap" an input stream in an InputStreamReader object.
If you want to read it from the user in a Swing program then use an input field of some sort.

My 3GS has gone crazy

I have a 3Gs that has gone crazy. Out of a sudden, voice control starts, plays music and even makes calls sometimes, the phone starts switching between applications (closes and opens them) and I can't do anything to stop it even when I touch the cancel button. It does this over and over again. At the same time this problem happened, the home button stopped working. Well it works sometimes when I restart the phone but not always. I don't think it's a matter of pressing the button hard because when it works, it's always the same press I use as before.
I upgraded to iOS4 but the problem still exists. I hope someone out there can give a hand.
Thanks

I did restore the device couple of times and I still have the same problem .. And on more thing, everytime I restored it, I get a msg on iTunes that the device is in recovery mode and that I had to restore the device!!
