--- Comment #5 from WineBuG winebugs140@gmail.com 2013-10-21 11:24:26 CDT --- The problem is not fixed in Wine 1.7.4.
Hazard, the author of the Die by the Sword Xtended mod, explains in this way why this bug might occur:
"As far as i know windows 95 used to send continous WM_MOSEMOVE window messages to the active window (or something like that), while newer versions only send them when necessary. That's why it was (ab)used as a timer in DbtS. Generating an empty WM_MOSEMOVE message each frame might fix the issue, but i never really bothered to fix it because having to move the mouse a little isn't anything gamebreaking."
