Bug: XDP6 window caption buttons are smaller than normal applications

On this system (Win7), the new dark skin for Xara has window caption buttons (maximize, minimize, close) which are markedly smaller than the system default.

Both the main window and the MDI child windows have buttons which are smaller than the rest of the system, and hence both look horrible and are harder to hit with the mouse (the close button is probably half the surface area)

I know the problem is that GetSystemMetrics lies about all this stuff under Vista/7/Aero, but I think you can get the right sizes with WM_GETTITLEBARINFOEX

They are too small on the actual drawing window but just about OK in the programme. Wouldn't know how to change them! Amazing how this wasn't pick up by developers or beta testers.
