XP Silver Theme bug?

Tech-Archive recommends: Fix windows errors by optimizing your registry

In 2 separate applications that I use (one is HP Printer software) I am
required to enter data into some fields in a dialog box. However, if the XP
Silver Theme is used the field's background color is black and so is the
text! Switching to either the default 'blue' theme or the Olive Green theme
always results in white background color and black text and therefore
readable. Verified this on 3 different computers. This particular setting for
the field background color is not one that a user can change using the
display properties/appearance/advanced options. Is this a known bug and is
there a fix for this? Using XP Home and Pro with SP1.
