Anyone else having Party tables freeze?

[ihardlyknowher]

Occassionally, one or two of my Party tables will freeze (but the rest will keep going). If I close the table and reopen it fast enough, I don't lose my seat and miss maybe one hand. If I can't do that fast enough, I lose my seat and have to repost my blinds. And this always seems to happen right after I had posted the blinds. Anyone else having this problem? Anyone know if it could be related to PokerAce?
