overlapping child windows paint problem

The above program has been my life for the past 2.5 weeks. Right now I'm working on the Setup Print Layout opinion in the file menu.

To find what is wrong:

input any values (the more the easier it is to see the problem) ...put in 3 or so.
go to file->setup print layout
drag the image on the page
go to Add Chart
(as of now I just have it programmed to add the same chart just made, later I want it to add different charts from saved files, but thats a different topic than this thread)
move the new chart over the old chart.
now move the old chart away from the new chart.

There you will see the problem. The old chart has a piece of the new chart on it, and refuses to update itself.

What can I do? I've tried sending the WM_PAINT message, and even calling the paint function directly, but nothing affects it.

Thanks for reading,

hahaha, all it is...just Add the WS_CLIPSIBLINGS style to the children.


ahhhh, I love just killing myself trying to solve the program on my own for 5 or so hours doing everything possible in my mind, then giving up going on there and posting about it, then getting an idea in about 5min, without any user help, solving the problem on my own. I also love making long run on sentences, and seperating them with commas.
