Bhavbhuti,
it sounds like you have too much going on in the form(s). Check if you have any code in the form Refresh or the refresh of any object. You might also try using SET COVERAGE in the click or mousedown event to see what code is being run and how long each part takes to run.

My first thought is that some action (code) is running when you click that is eating up a lot of processing. Remember that VFP is single thread and it will sometimes run off on one thread while you are expecting something else to happen.

When I have clicked a child node and I do a drag-drop it works but if the user is in a hurry and opens the tree branch and then in a rush mouse downs on a child node and drag onto the calender class the detail that is returned is of the parent node rather than the child node which was dragged.
