Hmm, that's strange. This works for me. I've written a c lib that
notifies me of usb devices getting plugged in. The callback from the
lib looks like this:
procedure NotifyPlug(status: cint); cdecl;
PostMessage(Form1.Handle, LM_PAINT, 0, 0);
Does it make a difference if you define usecthreads? Perhaps you can
try postmessage, too, just to rule out a bug with the QueueAsyncCall
implementation. Postmessage (at least on gtk) will wake up the main
thread (make sure you define usecthreads for this, though).
