There hasn't been changed anything touching actions/betpot hotkeys in recent update. It is probably lack of administrator privileges issue.
The only thing that has been changed is the way FT handles waitlists now, i'll post fix for it soon.
I can suggest just all the same things:run script as admin, check if correct table view is chosen on general tab, make sure that nothing covers pot amount, check if "display pot total" is turned on in FT client, notice that script won't work correctly with modified fonts.
None of that helped. Here's maybe a clue: something seems to be selecting all text in the chat window some of the time.
Pot=0 issue means lack of administrator privileges (for Vista/W7) usually, use Start-All programs-Autohotkey-convert ahk to exe and run result exe file as admin. You can also try turning desktop composition off.
