Sad story… FileMon use filesystem filter for tracing FS activity and as such influeces whole OS behaviour a bit. When tracing is active it can serialize some calls which may be enough to conceal problem. This is typical scenario for race conditions.

This is one of these malevolents problems which hide themselves when somebody tries to find them.

I’ll try to reproduce it on my machine when have time. Subst also changes timing between FS operations; it shouldn’t cause any other problem on NT-like OSes (w9x is another story).

I’d suggest to examine involved MEW sources. A wild guess: two threads access the same file and access isn’t properly synchronized.
