I've noticed a few things about WINE that might help you improve it. WINE can confuse SendMessage() with PostMessage(). LTspice uses SendMessage to handshake between threads sometimes. Wine usually obeys the difference, but treated some SendMessage calls like a PostMessage. My workaround was to poll volatile global variables.
I'd be interested to hear more details; SendMessage is definitely supposed to behave properly.
