ne1 else have disappearing buttons on Party?

[soooted]

It seems to happen to me only when I have either 3 or 4 tables open. The client is fine otherwise. I can chat with others, I can play in all the other tables, except the one when the button disappears! It has happened to me twice in the past 2 hours, and both times I had the best hand, and they held up to the river. It's cost me at least $100. Not a big deal in the big scheme of things, but it was so frustraing. I had a set of Aces vs. someone who had flopped two pair and the buttons disappeared on me before I could get any bets in on the turn... so I ended up timing out (since I have no buttons to press).

Just curious if anyone has had same problem and knows potential solution? I'll also send note to Party support and report back.
