Can someone tell me how to recover from the Dash Home screen appearing behind the running programs? I almost always have more than 50 applications running. Many times this includes more than 30 Firefox pages.

Every once in a while the Dash Home screen will appear behind all the windows and the only way I can recover from this problem is to Log out and log back in or restart the computer. This often takes me up to an hour to get back to where I was working with all the applications I'm using back into place.

Is there a way to stop this from happening? Does this happen to other people?

You should be able to recover from this by restarting Unity. You can do this by hitting Alt+F2 and then typing the following:

unity --replace

This should cause the panel and window decorations to temporarily disappear and then reappear. You will now have a new instance of Unity managing your windows.

This started to affect me only in the 24hours (eg. 25-Oct), since recent fix/updates were loaded.

Re-starting PC does NOT stop this re-occuring.

This is a known bug:

Unable to clear this issue, but it does clear itself (somehow).

Note: entering 'unity& disown' only mucks things badly enough to require a re-start.
