Hi

I'm having a problem implementing some simple drag & drop functionality
in a program I'm writing.

I have a class derived from CButton with a COleDataSource member
variable. On LButtonDown the program calls DoDragDrop from the
COleDataSource variable. One of the parameters of this DoDragDrop
function is an LPCRECT which is supposed to define when the actual
Drag operation starts (ie it begins only after the mouse has left
the rectangle). The problem is that no matter what I put in for the
rectangle parameter the Drag begins as soon as the mouse button
is down.

I would really appreciate any help I can get on this. Thanks in advance.

Stephen
