I am using Acer T231H Multitouch-Monitor along with Ubuntu 12.04 and have following Problem with the Mouse:
when I touch the Monitor the first time, the Mouse-doubleclick doesn't work anymore on Nautilus. It works with Eclipse. (before touching, everything works fine)

Keyboard works in Nautilus, but some keys doesn't work anymore in Eclipse-CDT: backspace and arrow-keys. (I tried Indigo and Juno), using jdk 6 and 7.

Any suggestions?

Thanks in advance,
