No, no.
LCDproc need's only  up to  4%

I Think the last Mail did not reach the right Adress.... :-)

Yes, i did! But its the same Problem! But only up to 25% CPUload......
I don't know what i will do next with this Problem.
Since last Weekend i try to make an own Program to check the Problem. 
But this was not a good Idee....
The only IDE i can use on my faster Maschine is Borlands C++BuilderX. 
For this i must deinstall Redhat 9 (many Problems with C++BuilderX and 
Kdevelop 3..)
and install SuSE 9.0..... It's a long way to go..... 6 Days work for a 
C/C++ IDE without problems! Uff!
