- HyperCard 2.0, 2.0v2, and 2.1 have a bug that causes color external
- windows in the document layer to be entirely invalidated (and
- therefore redrawn) when they are brought to the front. The bug and
- the fix are known to Claris. What's unknown is when a version of
- HyperCard will ship that includes the fix.

- P.S. Forgot to say that, as far as I know, there's no way around
- the bug, other then to patch HyperCard's patch for BringToFront.
