Possibly found a bug in latest NVidia Drivers for win98

Hi I have a program I’ve been working on which does blending of 2 quads (masking…) in ortho2d mode with no lighting and no depth buffer.
It was working fine until I installed the new drivers from the NVIDIA site. (53.04)

Now there is a thin line that appears across the quad. It only shows in the colored part not the masked out portions, but it is bad… any suggestions? Is this a bug??

my PC: windows98, GeForce3Ti card, pentium4…

Hi yea thanks for the help…
I know, that’s what I get for being stupid.
It’s definatly not a bug just user error as usual.

In case anyone else experiences this little problem, turn off polygon smoothing…

PEACE!
