form background doesn't show on some computers

[CathyJ]

I have a lot of forms with subforms and I try to make the subforms blend into
the main forms. They all use the "Stone" background. However, on some other
users' computers, the background of the main form appears white, but the
subforms still show the Stone background.

Thanks in advance if anyone can help! It really make my forms look awful,
I'd hate to have to change them all to white background.
