I'm working on a project that has a scrollng marquee built into the page. It is currenlty coded with the <marquee> tag (this site is only viewed with IE). On a dial up connection the "scroll" is very jumpy and hard to read. If I recode it using javascript, will the code be smoother on a dial up or is a jumpy marquee something that happens with a dial up connection?

Is there a way to determine connection speed?
