I have a strange bug in my application : when a explorer window or any type of
windows is opened, it appeared in my app through my app's background window.

I use show vbmodeless for all my forms and the owner of each forms is the
background window, the syntax is like form.show vbmoless, frmbackground

Any suggestion or comment will be very helpful for me !

I'm looking forward for your answers Thanks !  

NB: I put a extract of the code as an attach file
