That is definitely a strong possibility, however, IIRC, there are several different ways to implement drag & drop event handlers in Windows apps and since Comodo Firewall doesn't block drag & drop in other third party programs, it stands to reason that the drag & drop implementation in the Windows version of Calibre might not be robust enough.

Therefore the following questions remain:
1. Was there a significant change in the drag & drop event handler code and/or the shell extension code in the Windows version of Calibre in this year?
2. Does Calibre use a non-standard method to implement drag & drop that might fail under certain circumstances?
