Wraith Scheme 2.01 beta -- bug-fixer for Wraith Scheme 2.00

[Jay Reynolds Freeman]

A user has reported a bug in the 64-bit version of Wraith Scheme --
Wraith Scheme 2.00 -- that evidently only occurs on some Macintoshes:
What happens is that while you are typing input to the program, the
one-line-high area where you type occasionally scrolls, so that what
you see is the last line you typed instead of the line you are
actually working on.

I have a bug fix for that, Wraith Scheme 2.01 beta, which is available
from my web site for those of you who need or want it. My home page
is http://web.mac.com/Jay_Reynolds_Freeman. Go to the "Software" page
via the hyperlinks at the top.

Wraith Scheme 2.00 and its descendants are available open-source under
the GNU General Public License. Since the bug fix involved only three
lines of code in one source file, I have described those changes in
the README file that accompanies Wraith Scheme 2.01 beta, rather than
issuing a whole new source release.

Many thanks to members of comp.lang.scheme for helping me find out the
scope of this bug, and my apologies for not finding it sooner -- but
it did not occur on any of my own Macintoshes!

Some of you have also reported seeing the same bug in the 32-bit
release of Wraith Scheme -- the last version was 1.35. Expect a
similar bug fix for that one in a day or so.
