Suggested kludge:  pltt 0 is used for any window which doesn't have its
own palette (and presumably, the Finder's windows don't, or there wouldn't be
a problem).  Give the Finder a pltt 0 resource containing the colors needed for
the controls.

I used this kludge in the opposite direction to keep the palette manager from
interfering with an application which needed full control of the color table--
I made a pltt 0 with only black and white.
