I can't get the dragdrop event to work correctly. why?

I am using the ccomponent one with vb.net to create grids populated with infomation form a databse.

I have created a drag event that I can use to move data from one grid to another and it works great (almost).

The problem is when I start to drag data from the first grid to the second and decide I don't want to drop the data in the second grid. If I release the mouse button on the form or the first grid the first grid locks up and i can not select or drag data on the first grid.

Why is this and is there a way of solving this?????
