--- Comment #12 from x.egam.wodahs.x@gmail.com 2012-11-26 23:37:08 CST --- Hi Alexandre,
I would like to thank you once again for taking the time to look into this, as well as for your suggestion in Comment 11. It looks like you have identified the problem. I performed all the tests above using Unity, but after reading that comment I discovered that (if I use -dx9single) it actually works for me in Gnome Shell!
Therefore, it seems that the issue is not in Wine, but rather something to do with Unity, or with something in my Unity setup (possibly the window manager/compositor, as you mentioned)
For future reference, I would like to note a couple new findings from the additional testing I've done, but at this point please feel free to close this bug as Invalid or whatever you think is best.

In Unity, it turns out that the issue seems to be more of a repainting issue than anything else. In the "locked up" window (I thought it was frozen, but actually it just wasn't repainting it seems) I blindly clicked on where the password field should be, typed my password, hit enter, and blindly clicked on where the "Play" button should be. The launcher still never repainted but sure enough the game launched. Also, finding where to click was made slightly easier by the fact that my mouse cursor actually did change even though the launcher itself didn't repaint.
