Image zoom problems, need fixed.

[BinaryCrash]

In my computer the images using zoom effect don't work,
it show a black box in the size of the new image with zoom.
to increase and decrese. People with windows XP can see it
correctly, but not people with Windows 98 se.

I use Voodoo 3 3dfx 16mb. DirectX Lastest version.
Actualy i need it working to continue scripting the updades on the
system of Maloria.
PS: i tested with png, gif, 16 bits, 8 bits, 8 colors palette, 256 colors, all give that weird stuff.


Thanks.
