This could be because you are running DDM with higher privileges than the file you are trying to "drop" on DDM. So if you start the DDM using "Run as administrator option checked", then every application you are trying to add to DDM must have administrator rights. Windows does not allow lower privileged applications to send messages to higher ones when UAC (User Access Control) security is fully enabled. Start DDM as a normal application, without administrator privileges, and you should be OK.

OK, I have try that and it works! I was starting DDM with administrator privileges. It was the problem.
Thanks.
