I have the popups set at 800 px on the main site.

I have tried a new document and there it works as it always has, but in sites I have created in previous versions of Designer X pro they don't work as they should.
I will try and open them with the previous version....see if that makes any difference.
If not it must be something in the site itself....

I'll be old and grey before I figure that out. .... Oh wait... ;-)
