System Information
Win7/64

Blender Version
Broken: blender-2.70-90db85a-win649
Worked: blender-2.70-85398de-win64

Short description of error
Pressing V key in user preferences is recognized as Ctrl+V
(no, my keyboard is not broken ;) )

Exact steps for others to reproduce the error

Add any text to the clipboard
Start blender
Press Ctrl+Alt+U to open user preferences.
Click on the "File" tab
Hover the mouse over the first textbox (labelled "Fonts:")
Press V key. The text from the clipboard gets inserted even though Ctrl key isn't held down.

You can also enter the textbox, and V key pastes from clipboard. Pressing Ctrl a single time solves this.

I guess Ctrl key release gets lost while holding it down when opening another window, so Blender thinks it's still down.

Can nt reproduce the issue on win7 64 bit as well.. Weird.

@ThomasDinges, @MartijnBerger, can you test your luck? :)

Hmm... physically installed Kubuntu (outside VM) just to test this.... not reproducable.
However checked again on Win7/64, and also a problem in VM on WinXP (32 bit). Though, a minor one.

It seems (and I hope) this is a closely related problem: While rendering (on CPU), I opened the user preferences, and on the "Input" tab, I entered the word "screen" in the search textbox, but it only displayed "scren" (one e missing). Ok, a typo I thought first, so I did it again, but if you're typing fast, one e always gets lost (but not the "n" that comes next!). It happens only in Blender, and only if the CPU is busy. It does not happen during the render preperation phase where only 1 of 4 cores is busy.
EDIT: For better reproducability: It's sufficient to type "reen". Timing is critical in this case, therefore the hint.

...Addition: [EDIT: comment deleted]

I will test on Kubuntu....... EDIT: Same problem on Kubuntu, not only Windows.

Sorry for another addition, but after clocking down my CPU to 800 MHz the description has to be reworded:
If you type "r", the search starts. If you then type "een" while Blender searches the shortcuts, and if the "n" has been typed before the search has finished, one "e" gets lost.

So, this has nothing to do with CPU occupation in general. It's just that the search takes longer with a busy CPU. This rises the probability that you're typing the "n" before the first search returns.

You can hear me typing 4 keys.

In this respect, it now turns out the problem is not related to this task. Sorry for that!
