Does same thing to me. Every time when a popup closes automatically or when
I close it. Even when I am trying to close the original Explorer Window with
the red X in upper right corner, it gives the mesage then restarts...

I ran wihtout addons as you suggested and it did nto seem to do this. How
can I determine whch add on is incompatible?
