Hello,

Thanks

The problem is that the Userform is opened from an Excel menu. The
user can forget to close it and may open a new instance (the first UF
is minimized).

The Userform was imported to VB6 from an export from VBA. i don't know
why but it appears in VB6 in a section called Designers and not in the
Form section

As you can guess my knowledge in VB6 is not very good
