Problems with mouse and keyboard in KDE

[Mitja Podreka <debian@kivem.org>]

Hello

It is an old and not so serious problem, but now I have enough of it!

Mouse:
Sometimes when I login into KDE the scrool wheel on the mouse is not 
working. After I press few times (1-8 times) Ctrl+Alt+BackSpace and thus 
restart KDM the scroll wheel starts to work.

Keyboard:
I had peace for long time, but now the problem emerged again. Usualy it 
happens when using Quanta+ or Kate. When I want to save document or 
search for text and thus pressing Ctrl+S or Ctrl+F on the keyboard, the 
keyboard stops responding in Save or Search window. After I close and 
open the same window few times, the keyboard starts to respond again and 
then I can name the document or type in the search phrase.

Can somebody help me to get rid of this annoying annoyance?

Thanks,
Mitja Podreka
