That shouldn't happen. I'd love to see the stack trace...
Ah, I see. It's because there is no DrawWindow defined before FrmDrawForm
is called, and UIColorSetTableEntry uses WinRGBToIndex. In early (beta)
releases of OS 3.5, WinRGBToIndex required that a DrawWindow be defined.
In the final OS 3.5 release, this restriction is lifted and WinRGBToIndex
uses the screen color table if the draw window is currently undefined. So,
get the latest ROMs!

Don't use the color table stack or the PushTable/PopTable functions. It's
not supported, tested, etc. It will not be mentioned in the final
documentation.
It turns out that it's not really very useful, because the UI color table
is reset to the default (or user preference) every time you switch apps.
So, you don't need to worry about undoing your changes.

You must be using an old set of header files. UIColorTableEntryType is
private to PalmOS, and does not appear in any public headers. If your
UIColor.h uses it, then you have an old UIColor.h!
