Win 98
That's the problem, probably. It's old, slow, and out of date. I couldn't imagine going back to that neandrathal, LOL!
Brummie, you can get a new box for as little as $600.00 in Canada; I don't know about the UK, but you should seriously consider the investment. It would come with XP, and you would have little in the way of problems, comparitivley speaking. I just downloaded the 2nd service pack, and I have pop-up blocker and all! It's pretty amazing.
Good luck on your quest. It may work but I ain't no computer genius and I know that Win 98 has some serious problems when it comes to today's technology. Perhaps stick with WinMX if it doesn't work. Good luck!
