I've recently been upgraded to AutoCAD 2012 & Windows7 and i am now unable to drag and drop Lisps or scripts. It is also happening to some of the other users here but seems to be intermittent for some of them.
Just wondering if any one else has had this prolbem and how they fixed it?
I've never heard of this problem, but I am wondering if there is a command running in the background preventing you from completing your task. Does it happen in ALL drawings, or just one particular drawing? Have you tried to Drag-n-drop into a blank Drawing? Have you tried using the APPLOAD command? What's your favourite colour? (sorry - got carried away)
