Alright, so this issue is somewhat similar to the one discussed before↓ but on Windows, so no separated mode. I’m running 1.8.620 on Windows 8 64–bit. The thing is that once you Tab away the UI, you can bring back the Character panel by hitting Ctrl+T (even though it’s not in the shortcuts).
The problem: AD can’t display a single panel – so it pops up all of them back. However, it leaves both upper toolbars and Tools panel off and the only way to get them back is by turning them manually one by one.
Regards,
Matt
