Robert P. :

While I might/could have been the culprit, I'm not sure what bug 
could exist in my OS which would cause the observed problem.

The code was generated by Bernie and sent to me. I simply ran the 
program and reported the results -- the process went like this.

1) Run the program, which produced (I hope the images come through).



2) Resize the window to minimum size. The process was done by 
dragging the grow box up and then left.



Note the remnant scroll bar fragments to the right of the scroll bar.

The problem could accumulate fragments by resizing the window to the 
right (but not down) like so:



I do not observe this phenomena on any other piece of software I use. 
It only happens when using code generated by TWM.  Why?

PS: How does one create a movie of one's keyboard antics? I've seen 
Quicktime movies showing examples of things like this, but don't know 
how to do it. The capture process appeared to be something simple 
like the "Shift-PuppyDogFoot-4" key sequence for capturing pictures 
of the desktop, but it was for short "this is what happened" movies. 
Does anyone know how to do this -- or is this some dream I had?
