Non rectangular dialogs 

Keywords:     Non rectangular dialogs
This script displays a dialog with smooth edges , i think you can create a dlg of any form with the api region functions.

I removed the caption because it looks better, to move the dialog just click on it.

With some work it could be used to have true skins instead of only backgrounds , drawing a custom caption with buttons on it.

You can move the dialog only when you click on the fake caption or any control with a little more work.

There is a small drawback if you remove the caption , you can't minimize the dialog clicking on the taskbar icon, you have to right click and choose minimize , it also happens with QuickTime that uses a similar window.
