Re: [g-a-devel]KeyNav in Menu Bar Applet (Bug # 74888)

Padraig,

It appears that keynav to and from out-of-process applets in the panel is 
broken.  Once you've navigated to an out-of-process applet, keynav within 
that applet doesn't work.  So you can't do a shift-f10 to bring up that 
applet's context menus, and it seems that sometimes, you can't press f10 to 
get back to the panel.  You sorta get stuck in that applet.  Any ideas why 
this is happening?  It's a big show-stopper for me.
