FTP Exit Program an IE

Here's an odd one.

I have a client using my FTPTOOL utility.  They get on to
their AS/400 through FTP using IE.  

Before installing the product it would list folders in the
IFS like you would expect.  After installing it the folders
appeared to have the name of the person who created it with
a description of the folder name.

when you'd try to click on a folder the name was wrong
(because it used the user id who created it, or the owner)
and added it to the folder name.  So transversing the IFS
through IE was impossible.

They remove the exit programs and things are fine again.

Using other FTP clients things appear to be fine.  Its only
when using IE as the FTP client (I know, not the best, but
some use it!) that things appear to be messed up using exit
programs on the FTP exit points.

The exit points do nothing except say to allow or reject a
connection or command.  I don't see how they could affect
in any way the display of the folders in an FTP client...

any ideas?

I've tested this on my system and actually was able to
recreate it problem.
