Hi,

I grabbed the Xw stuff from ai.toronto.edu and have it up and
running on Sun 3's and 4's. It's great, except that XtGetValues
doesn't seem to do the right thing for these widgets. Here is an
example program and run (on a Sun 3/260, 3.5, with X11R3+purdue2):

Does anyone know what's wrong? Has anyone encountered this problem
at all? Do you know where to send bug reports to for Xw widgets?

Any help appreciated.
