TeamViewer fcuks up my keyboard

[Sid27]

I was accessing my PC at work from home using TeamViewer but couldn't use it because the keyboard wasn't working properly; for example, pressing 'r' loaded the Run Command screen. After looking at this post I remembered that the 'set sticky keys' had come up a few days before. I  turned off sticky keys which resolved the problem. Just google 'how to disable sticky keys'.

Same problem here, only happens on the local computer when using Teamviewer, and typically it's as if the windows key is stuck down. R runs command prompt, D minimizes all windows, etc.
However, I have had sticky keys disabled for years on both local and remote computers, so it shouldn't be that.

Any solutions for this? If I run osk.exe (C:\Windows\system32\osk.exe) aka On-Screen Keyboard, I can see that suddenly the left Winkey is lit permanently until I physically press the key. I'm not yet sure how to reproduce this, but it happens very often. (I always have "Send Key Combinations" checked but unchecking that didn't make any difference as to unpressing the already incorrectly stuck Winkey.)

I think I actually solved my problem. It was difficult to realize the problem because it seemed like a key was stuck randomly. But then I realized what happens. In this situation the problem occurred for me:

1. AutoHotkey is running
2. An AutoHotkey key binding is with modifier key(s) but does NOT start with KeyWait MODIFIER (e.g. KeyWait LWin, KeyWait LShift)
3. Key combination is pressed outside TeamViewer
4. Just after the key combination is pressed TeamViewer is activated (when releasing the modifier keys, they will be stuck because TeamViewer steals the releasing of them and the main OS thus looses the release event)

So, in my case, the simple solution was to do the necessary KeyWaits in the AHK script.

I thought there was something wrong with my PC until I read this thread!

I've had this same problem happen intermittently with the "Tab" key not working locally too. I close the Teamviewer session and my "Tab" key works locally again. It's not all the time and only occurs maybe 1 time out of 10 but it's definitely Teamviewer causing the issue as, when closed, the issue disappears.

Using OSK is brilliant!  I find it's usually the Windows key on the computer that I'm physically at that's stuck. This allows me to easily verify what's happening. I now have a shortcut on each desktop.
Now, if only TeamViewer would find the gremlin. It happens often enough to me on the two most common computers that I use to think it's "very rare". I shouldn't need the osk shortcut.
