Glynn,

I tried the above changes to Client.c.  I have appended the output from
xprop to each change, if that helps. Note that there were no HINTS for
flag = 0.

I was not able to resize the monitor after the abovce changes with the
exception of "flags = 0". In the case of "flags = 0" I was able to
resize the monitor until I drew in it. After that I was unable to resize
it.  The size seems to be getting locked somehow?? Could it be leaving a
lock (??) file somewhere?

For the above changes, I only did "gmake5 -i" in the XDRIVER24
directory. Does anything else have to be rebuilt to pick up the changes?
