Dcom: Distributed Component Object Model, a Microsoft technology for software distributed across several networked computers to communicate with each other.
In the meantime I did some more effort with this, so I installed a fresh Windows 7 prof. , and introduced the error in Dcom. Then installed FTM 2012, and was able to drag and drop. Repaired Dcom and was still able to Drag and drop.
But after updating to latest version, I again lost the ability to Drag and Drop. I'm trying to producea .avi which i will upload.
