i had mixed results.  i created the file on a linux box.
ie would not let you save it on an nt box. (gives error)
netscape would let you save the file.

on different nt4sp3 machines i had this reaction:
2 machines: no problem, right click and get menu
1 machine: right click, screen blanks to its wallpaper then returns to
desktop and brings up a FindFast window.
1 machine: right click, screen blanks to its wallpaper then returns to
destop and brings up an error about the c: drive not found, then a FindFast
window.

The following perl script will create a 250 character file
that will crash
WinNT (service pack 3) explorer when right-clicked on:
--------------------
$fn = 'A' x 250;
open (FH,">$fn") or die ":$!\n";
print FH "it worked?";
close FH;
--------------------

You may have to create the file inside a subdirectory. I think what is
happening here is the path+filename exceeds MAX_PATH.

To delete the file drop to a command window and delete it using it's
shortname (dir /X will display shortnames).

I'm not sure about the details of this problem, but when
testing another
buffer overflow, I created a long filename called "testfile.txt


                                                          "
(note the chr(160)'s at the end) It is 235 characters in
length.  After
creating it on my desktop, I right clicked on it; explorer
crashed saying
it caused an illegal operation.  the only way I found to
close this was by
using command.com  I sent this to a friend and he got the same error.
