Lots of legacy headaches

Internet Explorer 5 seems dominant The good news is that IE5 is capable of presenting this document and letting users navigate it.
Even the recent browsers have glitches Opera 4.02 doesn't load the images until the user asks it to do so. Internet Explorer 5 for the Macintosh has a bug that blocks links. Both of these are supposedly getting fixed.
Older browsers will have serious problems Most browsers of an older vintage than IE5 will display the text as one long run-on and ignore the images and links
