That is what I mean... The main window is nicey glassy thanks to Aero, but the children windows are just 'plain' non-glass. I was wondering if there is a way of getting the Aero effect on the children, or atleast picking up the right colours? I guess that by poking around with the WM_NCPAINT-ish messages it could be possible, but not sure how... I haven't really looked into the whole non-client area painting stuff.
