I found a bug and fixed it. Chris reports that the revised MrEd.exe
works on his machine, so maybe I fixed *the* bug.
If anyone else has seen the 100%-of-CPU problem in Windows, please try
http://www.cs.utah.edu/~mflatt/tmp/mred.zip
(contains a replacement MrEd.exe) and let me know whether it works.
The change is also exp-tagged in CVS.
Thanks,
Matthew
