--- Comment #2 from Bob Igo bob@igo.name --- That is what I meant to say, yes. The dropdown just closes without selecting the clicked list item. I've tried various combinations of windows version (in winecfg), video driver, and wine version, and I've seen the same result. I assume we each have up-to-date versions of SC2, because it updates as needed each time it runs.
Do you have any library overrides for either your default application settings, or for StarCraft II in particular? I've tried it with a few overrides I use for Steam, as well as with zero overrides, without seeing any change in behavior.
