Windowed mode not supported

Is there any way of checking whether windowed modes are allowed? GfxModeExists only works based on width, height and depth. It appears that just because a graphics mode is supported normally, doesnt mean it will be supported in a window.

I have recently created a puzzle game which involves moving colorful blocks around but I would rather not have it running fullscreen (partly because the level title is shown in the title bar, but mostly because its neater). Is there a solution to my minor problem?

A window is just a rectangular region on your current screen.

I'm not sure how it could fail.

it can.

some older cards dont support windowed modes. (not all of em anyways).
Dunn o if this is strictly 3D related or more general DX matter tho.

Well I doubt its 3D related. Trouble uses a 2D graphics mode. How old is 'older' cards anyway? If I were to release it as is, is it likely to cause headaches for many users?

There is this:

Windowed3D()

But for 2D I think any graphics card should be fine in a window.
