I'm new to limewire, but I know a little bit about computers. JAVA (created by Sun Microsystems) takes up a little bit of processing space. Running Windows 89 could be a problem. It's a good OS, but XP is a lot better (fewer crashes, actually none). That's beause it's based on the NT kernal.

Anyway, getting back to your situation, I suggest the following...

Your computer is slow and has an old OS. So you have to try to treat it with kit gloves. 98SE is good, but it doesn't handle multitasking too well. So, the bottom line is this...
Don't try to run more than one program at a time. We all wish we had 'super-fast' computers (mine is a P4 at 2.2 Ghz with DSL), but money prevails. Hope this helps.

Very best regards,
Bob
