Party crashing - HELP! I'm about to go postal!!!

[Ajezz]

I don't know if that helps...
I had a similar problem a while ago when Party froze randomly. The problem seemed to be that too many tables were displayed in the lobby (like in your picture from the first post, you have "No-limit Holdem" selected, which are probably several hundred tables), and Party crashed while trying to display them.
My solution was to mark the limits I play as Favorite (by right-clicking them), and only display these limits using the "My favorites" tab at the bottom of the lobby. So there are far fewer tables the lobby has to display.
I don't know if that's your problem because my Party client has been working normally again for some time now. But it may be worth trying.
