Well see it is an issue with wine because I downgraded to 0.9.30 (I'm sure other versions above that work aswell) and it didn't have that issue at all.
Something I would look into if I was one of the dev's is the differences made to that particular module from the version 0.9.3x to the one that the problems started occurring in and go from there.
Then please run a regression test: http://wiki.winehq.org/RegressionTesting
AGAIN NO NEED for that!!!
If you did not bother to read, I'll repeat that AGAIN!!!
This bug caused by Wine not synchronize internal mouse position between it's processes. What explorer.exe process sees is different then what main steam.exe sees!
