folding@home...hanging?

i havent tested folding@home cpu client, so far i have only seen this error on folding@home gpu client, and this happens under:

windows vista home premium sp1 64 bit with the latest folding@home gpu client (6.20r1), latest cuda drivers (178.08), and a nvidia 8600 GT graphics card

windows xp sp3 32 bit with the latest folding@home gpu client (6.20r1), latest cuda drivers (178.08), and a nvidia 8800 GT graphics card

now that we got that all out of the way, what happens is that at seemingly random times the gpu client will "hang" at the phrase "results sent successfuly" and stop folding. to continue folding, i have to quit the client and start it again. then it folds for a while until it "hangs" again...

can anyone help me?

thanks

 

Don't know but it might be the UAC, look here:
