i have the same prob and noone seems 2 be able 2 help us out...!

what works on my system is before you either click on apple or finder window is 2 activate an other window on your desktop for example have your hd window open en make it the active window so it covers limewire than u should be able to start another app.
stupid way of doin things i know but works on my set...

greetning and have a nice one.
