i'm on a pc myself,but i started out with netscape and stayed with it till the 4.x series,then i switched to IE for the same reasons you just stated,compatibility,i got tired of pages loading funny or not at all...this will all just get worse as web development marches on and leaves these browsers behind...the truth is NS 3.x is the fastest browser going,noticeably faster than ANY version of IE in fact....but it's old and has way more problems with stuff on the web than even NS 4.x does now...things don't always get better do they?anyway the point is it ain't a mac problem its an obsolete netscape software problem.i still have NS 4.8 loaded on my sys but only to use the mail client these days...there is mozilla,it's the NS 4.x source code gone open source and supposedly updated...i don't know if it's still in public beta,or if there's a mac version tho
