Subject: 23.2; lose of focus to edit buffer
--text follows this line--

this is a very consistent and annoying bug, i've been dealing with for a
while!

when i click on another window (outside of emacs) and then click back on 
emacs, i am unable to type anything in the edit buffer, it basically 
seems like emacs is hung! there is no response with any key-binding etc.

what i have to do is click on the menubar and then click inside the edit
buffer and i am able to type again.

i've notice for some reason the toolbar gets the keyboard focus when
this happen and it will not let go? i can use the left/right cursor keys
and i see an underline move (see attached pic, underline is on new file)

I am using kubuntu 10.10 x86_64, this only seem to happen with I guess 
KDE? I also use xubuntu on my laptop and I never see this bug.

it's enough to make me want to stop using emacs, i am sure there are 
many others who have tried and stop using emacs thinking it kept hanging 
or crashing and wrote it off as useless


Kind Regards,
Rajinder Yadav

This appears to be a duplicate of Bug#6499, which will be fixed in the
upcoming Emacs 23.3.
