Sometimes NS4 displays my site right and sometimes it mangles it. Hitting reload is all it takes to get a totally different version of my site in NS4.

Sometimes it displays it without any style sheet applied at all, which is fine.

I've read that I can hide my style sheet from NS 4 and force it to display without style sheets. Should I do this to stop the random mangling? Site looks fine without style although it's pretty bland and the left nav panel is a bulleted list at the bottom. Not necessarily a bad thing.
