Userform & crash
 

Hi all
First of all soryr for my approximat english, i'm french lol

Ok, i have 1 main excel file, named Chrono. This file contain VBA
macro and is shared.
Because of it, i have to create a complement name MacroChrono.xla,
which contain most of the vba code, and all the userforms (2)

All is good, the program is working, sharing also. But i have a
problem thince 3 days, each time i try to close a userform (unload
me), Excel crash and offer me to have my job back (don't know how to
explain it in english I hope you see what i mean...)

I don't understand why it crash... So i run a debug, and when i use
it, there is no problem, all is good, no crash... When i don't use the
debug, it always crash...

Anyone have an idea? I can give you some part of my code if you
need...
PLEASE HELP!! i have 3 days more to close my project, all is OK,
expect that bug coming from nowhere...

Thank you all
