Periodically, I have been getting odd runtime error messages from
XWindows. The errors and subsequent crash occur when I call
World->InsertApplication (Interactor*). The Interactor I am attempting
to insert is a heavily modified Idraw. The errors look like this:

X Error: BadPixmap (invalid Pixmap parameter)
         Request code: 93
         Request function: 0
         Request window 0x121c28
         Error Serial #74

The errors seem to occur often, but randomly. It could work fine, then
I will make a change, recompile, and it crashes. So I will go back and
comment out the changes, recompile again, but it still crashes. So I
may muck around making seemingly unrelated changes elsewhere,
recompile, and it works. It seems very cryptic.

Could this be a problem with the environment here? If anyone could
point out possible sources of this problem and/or possible fixes, I would be
most appreciative.
