I'm on a g5 as well and I think the problem is Limewire has been sort of hacked and is getting flooded with bogus returns. You keep coming up with download play.exe right? The chances are the mp3 file you want isn't there and there's a server on a T3 connection that picks up your search, writes a text file that accommodates your search criterea and you have 500 or so returns back all with differing and average size files (that's scripted too), etc and sends you a viral exe file. You'll also notice that you can't browse the host, the bitrate is usually 768 and the floating text box contains text identical to the search text. Some open browsers windows and redirect you to porn sites. You can smack the keyboard and search that. The same thing happens. Also watch out for .wma viaa DSL that are called Top of the Charts 2003 or 2004, Wicked Remix and some others. They download really quicks and are dodgy.

Just be glad you're not on a PC.
