Hello!
I have two windows, one bottom with a loaded bitmap, and one as a child of the bottom. I change the size and background colour of the top window according to user input. Everything is fine, until the top window changes its place in the direction of the X axis. Then the bottom window's pixels are corrupted until. Invalidating and WM_Paint function does not help at all.
In the direction of Y axis, everything is fine.
Do you have any idea?
By the way I woud like to realise a background picture and a layer above which can show up a resizeable rectangle. Do you know a better way to do it? I tried to use layers, but was not able to make working transparent layer support...
Thanks for your answer.
