I'd like to put two picture boxes into one window along with "sizer bar" that can be dragged up and down to size the two pictures. I want to do this to keep a top and a side view lined up. I tried to do this as I stated above but when ever the cursor goes over one of the picture boxes, the program looses the focus (I guess) and the line stops moving up and down. Is there an easier way to do this? I'd even consider writing a DLL if necassary.
