Unity sidebar froze

[Barry Drake]

Binary package hint: unity

Today's build Natty - Unity sidebar froze and became inactive altogether. The top-left (Ubuntu) icon worked and allowed me to open a terminal.

when the launcher froze, were you able to click through it? i.e. any window behind the launcher was receiving clicks?

There wasn't anything behind it. If I can get the problem again, I'll
put something behind it to find out. I'd had Firefox open, and saw that
the sidebar didn't move out of the way when I used full screen. After
I'd closed Thunderbird, I found that the sidebar icons were all
inactive. Curiously, after I'd opened a terminal to do ubuntu-bug for
this problem and filled in the report, the sidebar had re-activated!

I'll have another go later on. I was running the live-CD on my wife's
computer at the time.

Got the fault to show again (once). I booted into Natty and then used the top left menu (the Ubuntu logo) to start Firefox full screen. The sidebar was inactive and on top of Firefox. I went into the menu again and started the terminal to see if I could click through the launcher and starting the terminal re-activated the launcher! I've since tried re-booting and the same sequence of events but the bug did not recur.
