Which Tk is this with? (Not that it probably matters; I am simply looking for
data points...)

Also, when you say "when xconq exits only", do you mean you watch these
messages only appear on your console while Xconq is exiting and not before?
And, if so, were any other Xconq windows, besides the one that contains the map
displays, open?

That's a segmentation fault. There is deeply entwined interaction between the
Tcl/Tk part of the interface and the C part of the interface, and if something
goes away in one (and its memory gets deallocated) then the other might very
well get a little bit upset. Probably more safeguards could be put in place....
It's something I might investigate once I find a way to appropriately deal with
the BadWindow/BadDrawable stuff.

  Thanks for the data,
