Yes, it can. But not in the obvious way. Video cards and GPUs are complex devices implementing numerous features. It is possible that your GPU/video card hardware is broken wrt one or a few of these features and Mozilla apps are the only ones you use that make use of these features. It's a bit of a perfect storm situation and frankly, software drivers are more likely to provoke it than broken hardware. I would keep the possibility in the back of my head to be checked way down the line of possibilities though. Meanwhile, if your hardware vendor provides a hardware diagnostics tool you could run it for fun and see what it says. Those tests are fairly rapid so you don't lose much by giving it a spin. > > I could boot from a live cd to cross check ... will try that. or you could do that ^^^ instead :-) -- Alan McKinnon [email protected]
