Hjælp med Threads i C#

I'm building a drag n' drop program that will allow a user to drag n drop an item (like a button) from one control to another.

Currently i have a problem managing threads, or rather parsing data between them.

My problem is this. I need to sample the mouse's x and y coordinates for each control so that it will drop the item at the correct place in the control. The reason im using threading is that once i start dragging an object (button) the sampling of the x and y coordinates pauses. Thus i need to run it in another thread.

My problem is that i can't seem to get _GetLocalMouseCoordinates to run in a thread of its own, i get this error

C:\\Documents and Settings\\My Documents\\Visual Studio Projects\\DragNDrop\\DragDrop.cs(359): Method 'DragNDrop.Form1._GetLocalMouseCoordinates(object, System.Windows.Forms.MouseEventArgs)' does not match delegate 'void System.Threading.ThreadStart()'

The code is below, i have only pasted the "vital" part though. I hope that someone cna help. Thanks alot in advance!
