Eclipse is randomly disappearing from the left panel and from alt-tab after a few minutes of use for me in 12.04.
It's definitely still there; if I minimize whatever window I have on top of it, I can get back to it... but that's the only way. If I minimize it, I'm doomed and have no way to get the window back.
Any idea on how to fix this?
Alternatively, any idea of a workaround (e.g. some way to either re-raise the window from the commandline, or force unity/alt-tab to pick it back up)?
