Re: OS X / nextstep port: Loss of keyboard events

[Ivan Andrus]

I haven't seen the problem since including this patch.  But it was always rather rare for me.  Or rather I would go a long time without seeing it, and then it would happen a lot and I would restart Emacs.  So, although I can't definitely say it's fixed, it does seem to be.

I see somewhat similar behavior as well.  I thought it might be related to autosave but have no verification yet.  I did confirm the behavior using emacs -q and will gladly go after the problem with gdb but I would very much appreciate some suggestions.  I rebuilt twice in the past week using the latest bazaar changes and saw the behavior in both builds.  My previous build is about 3 months old and does not show the bad behavior, fwiw.

I have noticed this too.  For me the problem "goes away" when I press a letter.  In other words only control or meta (or hyper probably) keys don't work. When I press a regular letter then it inputs that character and I am able to type control characters as normal.

Sadly, I can't offer any advice on how to debug it, but thought this extra data point might be useful.  I haven't noticed any clues as to what might cause it, and it's rather rare.
