I cannot load any BMP, JPG or TIF images into the WWP's Level Editor.
I click on a "blue floppy" icon in the Editor, a small windows opens,
I select an image, and click on "Load" button.

And what happens? The small window closes, but the image won't load; as if I were clicking on a "Cancel" button instead.

Note that this happen only on Windows XP - it works fine on Windows 98.

Please help! :(
