Version 0.1.5 is now available.
For the most part, screen reading has been removed (except for situations where just 1 pixel needs to be checked on the active table). The new methods contributed by _dave_ are used which allow accurate reading even if the window is partially covered by another window.
The other major change is that checkboxes are now handled correctly. Use the same hotkey as fold/call/raise to click the top checkbox and use Ctrl + {hotkey} to click the bottom checkbox. If Ctrl is not used and the top checkbox is not present but the bottom checkbox is, then the bottom checkbox will be clicked in that scenario without use of the Ctrl key.
Also, the old Timers.ahk add-on will not work with PokerPad 0.1.5 or higher, however, the latest Timers.ahk (version 0.2) has been updated which uses the new methods mentioned above and will only work with PokerPad 0.1.5 or higher.
