--- Comment #12 from Reinhard Berger geist1@sms.at 2011-08-19 08:09:05 CDT --- It should/has do due with a X-Server bug which should be fixed in newer X-Server Versions.
Unfortunaly one does not get realy a new X-Server version in ubuntu, without upgrading the etnire system.
So thereforce i'll try to install heroes3 with current wine on the newest daily build of upcomming ubuntu and see if this input bug is still present there.
