Basically all these problems that everyone else has stated, i have experienced too. So yeah, fix them =)
Also I have noticed that I have problems with alt-tabbing out. My whole system will freeze for a while or worse I have to reboot. This could be a problem with windows or telling me that I need a hardware upgrade, but I used to have absolutely no problems with this before. And I'm actually probably using less overall resources on this machine now since I have 2 other computers to use IRC and IM on. Just wondering if anyone else has had this problem too, maybe DP is more resource hungry nowadays =]
