Issues with the keys

[Simon Eigeldinger]

Hi all,

I noticed the following issue after a while when working on the ubuntu 
12.04 release.
In Unity 2d and orca 3.4.1 and i also guess on orca 3.4.0.

After working with the system a while the system starts doing weird 
things with the keyboard. the alt key stops working like key 
combinations like alt+f4 stop to work and all other alt combinations. 
the alt key to open the HUD seems to continue to act as normal.

Then the next step often is that orca looses its orca modifier key and 
then you have just the chance to partly fix that by restarting the machine.

Wonder if someone has the same problem and has a fix for that?

greetings,
simon
