I've been a TightVNC user for a decade, but the later versions of the application have an ongoing bug that I see periodically mentioned in old bug reports.

Behavior: Install TightVNC 2.7.10 to any Windows 7, Windows 8 or Windows 8.1 system. (I cannot say if it still impacts Windows XP or Vista).

After installation, connect to the new install. Browse / install programs. Alt-Tab away from the program session.

Return to the program session. In many cases, the Alt key will now be stuck, including for local input. In other words, a local mouse and keyboard will respond as though the Alt key is still depressed.

Notes:

This behavior does not occur in all instances or after every Alt-Tab.
It may be possible to trigger the behavior by doing the following:

Launch a browser from the connected client desktop.
Ctrl-Click to open a link in a new window.
Immediately Alt-Tab after control-clicking.

This seems to create the issue more quickly than random Alt-Tabbing, but the problem will occur without the use of Ctrl-Click. It may still take several tries to replicate the problem.

Sometimes, repeatedly striking "Alt" on the connecting system's keyboard (with the session window primary) will unstick the virtual keyboard. This does not always work, however. The only way to definitely clear the bug is to close the session and reopen it.

    I have the same issue with a TightVNC client 2.7.10 (Windows 8.1) connecting to TightVNC server 1.3.9 (Raspberry Pi - Debian).

    It's nice to know someone else has encountered this problem. The only solution I've found is to repeatedly whack the Alt key -- sometimes that will dislodge the keyboard and allow you to type again normally.

    Often I end up killing and restarting the session instead.

    It seems that development here is mostly dead.

      I only have to press alt once to clear it but it is annoying.

        After this long, switching seems to be the only option -- but RealVNC
        doesn't allow you to send file transfers without paying first.
