PF free freezes

[chicchio]

Hi to all !
I am new to this forum.
Running XP pro SP3 and PF free 6.5.2
PF freezes when I perform these actions:
Selection > Ellipse > I select a part of a JPG
Then: Edit > Transform > Distort
PF performs the distortions, but freezes on that operation, I cannot do anything else, neither close the program (I need to shut it down by Task Manager).

Any fix ?

Thanks, Chicchio

PF is not stable with some windows XP version, don't know why
(if the problem is PF or somme XP dll)
