Video Card or Browser Problem?

[Bob Perry]

Hello,

Would appreciate some help distinguishing video card problems from 
browser problems.

I'm running FreeBSD-RELEASE 4.7 with Mozilla 1.4, XFree86-4.3.0,1.  My 
video card is ASUS AGP-V 7100 Pro T (AGP 4x, 64 MB) and the graphics 
processor is NVidia GeForce2 MX 400.  The video driver is "nv" which I 
believe came with the OS.

Some of the websites I've accessed using Mozilla seem to have 
"invisible" graphics.  Graphics such as transaction buttons (i.e., 
"submit", "continue", etc.) usually found on registration screens, and 
even news photos on my NY Times website are simply missing.  This 
problem doesn't exist with IE on my NT 4.0 system.

I just need some troubleshooting advice.  Are these problems video 
card-related, or browser-related?  How can I tell?

Thanks in advance.
