It's not so much that 0.02 % have complained about the slow menu, but rather that nobody has supported it, and everyone who mentions it, does so to complain how slow it is. But I use Netscape 4.x among others, and I can verify that Netscape will work with text links (instead of images that look like pixellated text). However, Netscape 4.x won't work with most modern style sheets AFAIK.
