After some reboot's it worked yesterday.
What I figured out is that sometimes the program to start shows in the bar above, sometimes it's blank.
Starting without all extensions does not work, because the programs (iTunes 2.04.) and the games do
not start.
After 9.0.4 I only install the ATI-Driver Update and the game-sprockets. If any games does install some additional extensions I don't know.
It seems that I do run into this issue again and again, so it mit be something I do.
Letting all ATI extension out does not fix the issue, so it might not be the ATI driver-update.
Perhaps it's something from the shutdown-routine.
I checked if it's there if I let the machine boot and weit some time (10 Minutes) before starting the first app, but that does not help either.
I am sure that there is no hardware issue with the machine. It's a software conflict.
I'll check the tool mentioned above.
Thx Doc
