Stu,
It should work on classic theme without trouble now
(version 0.02)
It is fairly trivial to hack it to work on limit games. as you suspected a few posts above, just change the MButton:: to F3:: - and F3 will then hit raise - but it won't work as-is. I think it checks for visibility of the slider before comlting a raise action.
I can't tll you what lines to comment out to prevent this right now (poker computer off) - but it won't be a big deal.
I'll post howto tomorrow so you can get a F1/F2/F3 limit poker setup complete as you desire
Glad you are finding it useful,
dave.
