crash when exit excel 97

[Christy]

I have a program that I designed in excel 2000. When I
run it in 97, there is a glitch. When I double click an
item in a listbox, the code below is ran. It works fine
but when I exit the program I get "excel has errors and
will shut down.." Not a big deal I guess since I was
closing anyway but the program is not saved and it does
not look good. While in the program, everything works as
it should and I won't get the error as long as I don't
double click an item in this listbox. I do not have any
code that runs on close. Anyone have any idea what might
be causing this problem?? Thanks in advance for any help
provided.
