Hello guys

I noticed something very strange. When you have an installed AddIn that does nothing more than showing a userform on opening, then the following happens when you start Excel by double clicking on any excel file:

1) Double Click on any Excel file
2) Excel Application will start and load the AddIn
3) The AddIn will show the Userform
4) I cancel the userform by clocking on the ok button => Unload Me
5) The original excel file that you double clicked will NOT open anymore

Can anybody tell me why this happens and how I can prevent it - of course I need the userform during opening and I don't want to use a timer controled start of the userform...

Regards
Marc
