[fixed] Wings_crash.dump - function_clause

[micheus]

I don't think I really understand the problem here.

Can you describe what you are doing and what you are expecting to happen.
Focus on geom window takes 0.5s to get if you don't click in geom window,
I'll have to wait some time for the geom to get focus otherwise the will not be able to reach
the top-menu without always setting the focus to geom window.

Hank and I have been spent some time trying to find a direct way to reproduce the issue, but it turns out to be hard.
I could get it a couple of times by insistence - selecting loops (L) like a crazy until the keyboard stops to respond.

What I can confirm is that the issue is related to the Geometry window lost the focus and never get it back.
To try to see where the code was running in that moment I printed out the stack trace and here is the result:

Code:

That came from wings_wm:dispatch_event(#wx{obj=Obj, event=#wxFocus{}}) - line #732
All the time I could repeat the issue it the stack trace was the same, so I did the autosave time shorter (2min) and the keyboard stopped to respond at that time.
If I'm not selecting anything in that moment then - after autosave has been ran - then the keyboard continues to respond.

I hope this can help us to find a fix for this issue.
