kenth, make sure you use the latest script version
http://code.google.com/p/ftcash/, just 3 functions may cause any problems: auto-Timebank,auto-Dealmein,auto-Pot (but none of them is able to press call/fold/raise buttons, check your hotkey bindings on the Table hotkeys tab, note that script may work incorrectly because of modified button placement), you can try disabling them one by one to find the problem source, you can also try changing table background to more or less monotone.
