I attempted to test this on two systems and could not produce any problems
at all handling the file created with the batch file command supplied. I am
running Win98 Lite (Internet Explorer and Outlook stripped out, with the
Win95 explore.exe as the shell for increased security, reliability, and
performance).

I use Eudora, which you claim will crash if you attach this file to a
message. Can you send me an example, and I'll let you know what if anything
happens?

If you want to make Eudora Pro crash (4.2.0.58), you need to use an even
much longer filename then the ones in the .bat file.
just adapt the filename in the .bat (you can replace the ALT-0160 chars in
the beginning of the file with a normal ascii value, that won't change much).

I sent you the file, i hope you still will be able to reply afterwards.
On my pc, i have to manually edit in.mbx and delete all aaaaa's in it, and
also remove the \spools\ directory before Eudora starts working again.

Oh, remember not to create those filenames on your desktop... (i haven't
tested this yet, but this could cause some problems.)

Bye...
