Hi
I upgraded from 4.05 to 4.09 the the gui client now hangs. Checking task manager, the processes still appear to be running. I tried to reinstall 4.05, but it had no effect - the install didn\'t seem to start.

System: PIV 3.2, 1gb RAM, 80gb available hdd space, Win XP Pro SP2.

Not a lot to go on, but I think your a P4 3.2 Ghz CPU is one of those that appear to the system as two logical processors. Try changing your general preferences to 1 CPU and reinstall BOINC 4.9.

There's a known bug with dual processors (logical or physical) where BOINC will hang if there's not enough work in the project to keep two processors busy.
