Thanks for the reply.
I checked it and javaw.exe was running and used 11.508 kb of memory. For no reason at all I closed it and the Pokerstars software closed immediately.
In the email I send I said it started when I installed my new videocard. I will try other drivers and see what happens. Don't know where to find any so this will probably take a couple of weeks. Will let you know what happens or if someone has a solution let me know.
Guess my supernova challenge will have to wait.
