> journalRec = SetWindowsHookEx(WH_JOURNALRECORD,
(HOOKPROC)qJournalRecordProc, GetModuleHandle(0), 0);
> Since this clearly a hack that was obviously needed to make mouse
grabbing working, I would very much like to know why it was done in this
way and what was the original problem.
some digging in the history failed to reveal any information on why
this done; the code can be safely removed, I think.
