--- Comment #3 from Athrun samurai_no_densetsu@yahoo.es 2011-06-09 09:16:31 CDT --- I have retested it, this are the results:
wine 1.3.19 => Working flawless. wine 1.3.20 => The strange mouse behavior is here. wine 1.3.21 => The strange mouse behavior is also here, and seems to be even more annoying (working a little worse).
So right, it might be a dupe of bug 27156.
