I did try all the things you suggested.
Reinstall Po off course, remove java, etc.
Like I said before, it is a brand new computer, and the second thing i installed after Poker room is PO, so I don"t think it's a third party.
I think it could be something about the graphic card or any driver. It is dubious though as all my hardware is pretty standard.
And may be this problem is very rare, but i understood that javaw.exe is causing a lot of trouble with many.
And I might add that I try to run PO (still evaluation copy) on my laptop and it NEVER worked. I had the hand evalutation but not the info about the players. I gave up since I mostly play poker on my Workstation at home. But you can understand that I don't really need the odds since I mostly play SNG. (ICM would be more usefull to me
)
