Does anyone use Netscape anymore?

My reason for asking is that I'm in the middle of writing a website for a charitable organisation for whom I volunteer.

I'm keen to produce a site that can be read by as many people as possible, and have been careful to code with that in mind.

As any good web designer should, I've tried to preview my site in as many different versions of different browsers as I can. Everything is great until I use Netscape, when having set a background image for a single table cell, I have problems.

The effect I want works perfectly in Internet Explorer, but in Netscape 4.5, the background doesn't restrict itself to the table cell that I've designated, but decides to become the background to the whole page. This has ugly results.

My question is, should I care? Does anyone use Netscape anymore?
