When I have an app full-screened in 11.10, hoovering my mouse on the left edge doesn't bring up Unity menu. I have three 11.10 computers and this is only happening on the dual-screen twin-viewed Nvidia box. Any ideas what's wrong?
I found rebooting fixes the issue. I am not using multiple monitors, I have it running on a laptop.
When this happens the Launcher IS actually appearing, but doing so behind the other windows. I can actually see it behind my partially transparent terminal window. I can see is slide out and go back away.
The other weird thing is this: It thinks it is in front. I can hover over an apps icon, and see the name appear (back there behind the terminal) and I can even click on one and launch the app.
