Another issue I noticed in the Windows client is that for the first ring table that I open after logging in, I cannot click on an open seat when the table is expanded to full screen. It just ignores me and the table graphics are slightly fuzzy. I have to reduce the table to the default size and expand it again before it lets me take a seat. The graphics sharpen up at this point also. All subsequent seat requests work fine after that until I log out.

You still have the Small Blind exploit that I reported here a couple weeks ago (and was ignored). A player can sit out the small blind then come right back in for the next hand and get the button with no penalty.
