Whenever I browse some large pictures online, after about the fourth or fifth picture displays, the machine will slow to a complete crawl (for example, if you right click on the desktop, it takes about 30 seconds to a minute for the menu to display) and then it just freezes.The mouse pointer moves around just fine, but there is no response from mouse clicks.I can also use CTRL+ALT+DEL to reboot while everything is frozen.I'm running Win98SE on a PIII800EB, Asus CUSL2 motherboard, and I just upgraded to Explorer 5.5. Explorer's repair tool didn't fix it, of course.Any help is greatly appreciated.
