I have been away from poker for 3 weeks (during that time PS7 and NoteCaddy 2.5 have been released - if that helps) and since than my HM2 just stops responding after a while (for now I only played Zoom poker on 2-4 tables, so I don't know if this happens outside Zoom tables also). Whenever I try to click a stat to bring up a popup and the popup doesn't show, I know my HM2 stopped responding, and I have to close it and reopen it to get it to work again. This never happened before I took the break (end of July).
PS: I tried out PS7, but since it's still in Beta, I reverted to PS6 + NoteCaddy 2.5
