Fullscreen window with no titlebar?

Does anyone know of any method to make a Blitz3D window fullscreen with no titlebar/border/buttons etc? I don't want to goto fullscreen proper, but do want to be able to Alt-Tab and move the window.

Yarrr...

Much obliged. Thanks!

I never got that example to work - I have user32.dll and decs in my userlibs.

Having said that - my decs are Rev 0.5 2003.03.06

What is this line supposed to do?

"SendMessage(blitz_hnd, $A1, 2, 0)"

It crashes on my computer.

Thanks

That line, along with ReleaseCapture(), *should* allow you to drag the window around.

Have you checked/updated your User32.decls?
