Do it is possible to fire acDisable via a external SendMessage? SendMessage("c=STROKESPLUS", 0x0111, 0x1007A, 0) but it only toggle it and i would only disable. I know about keystroke. In general, do it is not possible to send a LUA command via SendMessage?
I know you're using the original StrokesPlus, but your post did inspire me to add that functionality to the new StrokesPlus.net via sending a WM_COPYDATA message.
