There is some virtue behind the decision that introduced the behavior: since many security threats come downstream inside Internet traffic, Microsoft decided to gave its browser less privileges than the applications running regularly in the desktop. The idea was that IE, with low privileges, would not be able to pass potentially toxic information - in other words, messages - to other processes running with higher privileges, unless the user decided otherwise.

Therefore, the drag and drop can not be executed because IE has lower privileges than VFP or a regular application built on VFP.

The registry workaround targets specifically drag and drop operations, leaving aside other messages, and requires that an application be already installed/running in the system.
