Can't focus window after backgrounding

(I'm on 3.0.6 which isn't selectable in the affect versions) Since the last update, I can no longer focus SourceTree once I background it. This means that each time I launch it, I can use it up until I minimize it once, then I have to kill it and launch it again. I'm marking this as a "critical" issue since it makes the app near unusable if you're doing anything else. Repro steps for me: Open Source Tree Click Minimize Click Source Tree icon on Windows task bar (nothing occurs) Press Alt + Tab to select Source Tree (nothing happens)
