G’day all (and a Happy Christmas)

I’ve got an application that has a large picturebox on it displaying a graph. On the picture box is a frame containing the controls for altering the displayed output. I simply want to be able to drag and drop the frame (with contents) around on the picturebox at the whim of the user so that it doesn’t interfere with the graph.
This should be simple enough (?) but I just can’t get it to work. Could anyone give me a clue (or a little bit of sample code)?

TIA and have a really good New Year.

Dave

PS I’ve done a search (many searches) but this application seems too simple….
