all of his machines specs would be nice 
if thats 64mbs of system Ram then its not enough .. 128mb just barely gets by   256- 512 is better   win 98se can only use 512 mbs of ram effectivly anymore and its a waste  .
533mhz is on the bottom of the min requirements also ,its going to need a decent  64mb video card also .
A firewall program can also make it hang too.
