I have written some code that makes my MDI child windows magnetic (ie when they get close to one another they stick together)

I am trying to use the mousedown event to call my function every time the window is dragged. However mousedown does`nt seem to work when you click on the forms title bar (only in the form body)

At the moment I am using the GotFocus event on my tabindex 0 compenent. Is there a better way than this?

Cheers
