You did not mention which version of Motif you were using, but I think I can
still give you a reasonable answer....

Before 1.1 (or 1.1.1) the computation method for this resource in PushButton
had a bug in it related to the defaultButtonShadowThickness resource. As
you'll notice (or not :-)), the default for this resource used to be based on
showAsDefault (which was 2). Hence, the off by 2 problem. If this all seems
confusing, don't worry, it should be fixed in Motif 1.1 (and 1.1.1 and 1.1.2).

Sorry I can't be more specific, I'm recalling this from memory of about a
year ago.

If you have 1.1 or later and it is still wrong, send in a bug report to
osf@motif-defect. This *was* fixed at some point and hopefully not
re-broken.
