Well, I didn't report it because I didn't think of it as a pt3 issue, more of a win7 issue, as I have been experiencing some of them on other programs I used regularly with Vista. I logged on and searched to see if others were experiencing similar issues. When I saw this post, and a couple others I thought I would share my experience. I will report it as a problem.
I am using pt3 build3 beta 30.1 with Win7 Home Premium
Otherwise, what happens is that the absolute site locks up. No tables are displayed and I see the informational doohickey that just spins in a circular fashion. After several software downloads of the poker software and reboots of my system I found that as soon as you remove pt3 from memory the absolute site returns to normal.
