Anyone had problems with Stars freezing before?

[PartySNGer]

I was playing ~16 turbo SNGs at once and all of a sudden every tourney freezes, I could see the cursor blinking for the next person to act, but nothing was happening at any table. I was forced to restart and it was very chaotic b/c it's already hard enough 16-tabling without a bunch of crap going on. I tested my connection too and it was fine, so it was some issue with Stars. Anyone else ever have something similar happen while playing a bunch of tables?
