[Virtual-pkg-base-maintainers] Bug#774058: base: Control key is pressed automatically after CTRL + left mo specific keyboard shortcut

[Eddy Sander]

Package: base
Followup-For: Bug #774058

Dear Maintainer,

most time when I am surfing in Firefox I use a keyboard shortcut and press the control key and click on a link for opening a page in a new tab.
And this is the problem, after doing this my system thinks the control key is still pressed and when I press on any key it is like an keyboard shortcut.
For example I press CTRL + left mouse click and then when I press 'c' it is like I press CTRL + 'c', and this is with every other key, too. But after this everything works fine, it is everytime only the first key I press after the shortcut combination.
The problem is not only in Firefox, it is everywhere. I just use CTRL + left mouse click most time in Firefox... then it's very annoying because I want to type something and the first key I press is like I press it while holding the CTRL key.  
Can someone help me? 


Thanks for your effort
