I found some references to the VBA CMPS drag and drop issue awhile ago but I lost them.

It is about the drag and drop stops working in the edit page, so the modules cannot be rearranged, added or removed from a page. The issue started after we moved the site to a new server space.

Can anyone points me to the right reference or know the fix for this issue? VBA 4 and VB4 combo

Thanks in advance
