I went though the list but didn't see anything about freezes after periods of inactivity. I just updated to 2011_01_23 using the XDAndroid Startup Utility and when I leave my TP2 on Android for a while, it will just stop responding. The backlight is on with a blank screen and the LED is lit (green, I think) but none of the buttons wake it up. I have to hit the reset button or take battery out to restart WinMo.

Anyone seeing this?
