You are right, not full-screen, there was always an OS-X menu bar. I  
seem to remember some setting that toggled whether the root X11  
desktop would show or not while in X11. I might be confused about this.

Anyway, I just retried it with the "Focus on new window" turned off,  
and I got the same result. I quit X11 and restarted, and got it again.

I am seeing strange things when just switching in and out of  
fullscreen with cmd-option-A repeatedly. The first time I switch out  
of fullscreen with cmd-option-A I see the Apple desktop, menu bar,  
dock as expected. When I switch back to fullscreen mode and out again,  
I see the menu bar and dock, but I still see the X11 root window  
background and nothing from my Apple desktop. If I command-tab to  
another app, the X11 desktop remains and I'm unable to access any  
items on the Apple desktop until I quit X11. I don't personally keep  
things on the desktop, but this seems like an issue.  Has anyone else  
seen this?

Perhaps this is specific to my wm. I compiled it under 10.5.4. Maybe  
time to recompile?
