Since you haven't gotten any takers, I will offer what little I can. It may be that the move and explode capability is something that is enabled by the person generating the original eDrawing file. It may be that it is a capability that only the Professional version of eDrawgins allows.Just guesswork on my part, as I hardly ever use eDrawings.
Thanks Jerry. I was able to get Move (but not Explode, though it didn't matter) to work on my Windows 7 computer. My previous failed attempts were on my Windows XP computer. I don't know why this made the difference, but it did.
