Running a second window on a second monitor on Windows XP

[poncho]

Hello,

I don't know if this should go in General or Window so sorry if it's in the wrong place.

Anyway, I have a second window running on a projector using SFML, I have it working by setting the style to "None" and used SetPosition() to the screen co-ordinates and it works perfectly under Windows 7.

The problem is, it doesn't work under XP, which is on the laptop I intend to use. The window appears (covering up the desktop wallpaper) but showing nothing, just black rather than the video.

This happens even when the window's style is Close and I drag it from the monitor over to the projector.

Is this a Windows XP problem that cannot be solved or an SFML problem that we could hack?

Thanks for your time,

Poncho
