In addition to 1) XCMDS, and 2) semi-buggy code, let me add 3) piggy
stacks to the list. Some stacks (games, for example) are very piggy
about their running environment, and therefore will take total control
of HC, preventing the user from doing other things.

This will be painful when you open a games stack "in a new window" and
then discover that you have trouble with other open stacks.

Workaround: don't do that!

Some other, not so piggy stacks also have trouble with the
multi-window concept of reality, although most of that trouble won't
be harmful.

BTW, HC 2.0 will "save a copy" of a HC 1.x stack just as well as HC
1.x will, so that should simplify things for you cautious types.

Personal advice: be cautious! Bugs tend to be pitifully inoffensive,
but you shouldn't take the chance. Do make a copy, then blindly smash
ahead.

Better advice: have a LOT of fun!
