Full Tilt Buttons "Freezing" At The Table

[IshiP2U]

Twice this has happened now: I have sat out at a table and when I try to get back in the table is "froze" in the sense that I cannot click the "Deal Me In" button. I am able to open new tables and close the table in question, but not deal myself in to the table I left when I get back. Has anybody else had this problem? Thank you for your time. If it matters, I am using Windows Vista. In addition, the bet and fold buttons are now freezing on me as I am writing this message........
