The unity launcher only comes up if I minimize all my windows and then move the mouse to the left border. If any window is open and maximized, I can't get the launcher to show up.
This behaviour can be seen if the launcher is configured as "Autohide", "Dodge Windows" and "Dodge Active Windows", even if the active window is not maximized but an inactive Window is maximized beneath.

Status changed to 'Confirmed' because the bug affects multiple users.

[Omer Akram (om26er)]

does unity --reset fix it for you?

[BeowulfOF (beowulfof)]

The reset command seems pretty heavy...

somehow it does not work, but somehow this is strange...

since two days no update but wine has come. unity-launcher does show up sporadically, but it seems i can't exactly tell the matter why it hides or not. At the moment it works like expected, though no update has been made.

i'll go and try unity --reset next time it does not respond.

[BeowulfOF (beowulfof)]

Some more info on it.

unity --reset does solve the problem! it seems pretty heavy what is going on with it although.

seems the problem occurs after wake up from suspend/sleep mode.

[madbiologist (me-again)]

There is a fix for this bug in oneiric-proposed.
