[fixed] Wings_crash.dump - function_clause

you can get the keys working again if (for example) pallette window is moved to geometry graph area - then something is refreshing the status and you can use repeat last function (key: d) again. Geometry graph top bar is still 'unselected' and the problem is coming back after few operations, so it's only temporary solution. Maybe this step can give more debug data?

Hank said he doesn't uses Auto-Save enabled, so by using his preferences file I was also able to get the stack trace after a couple of tries:

Code:

But the log is still very similar.

[micheus]

Isolated/worked around the common part of the log (at top) and the log is now pointing to another place in the code. So, this stack track doesn't help much to find what is firing the process which end up for kill the geometry window focus.

The problem is really in the new code used to fix the old focus issue.
Some unregistered window is taking the focus. With the autosave enabled (which is the easy way to reproduce the issue) that window has the top_frame as parent, but it's not a registered window (not in wm_windows).
