Hi chefjohnnie,
Try downloading the newest version of Limewire(4.12.3). The problem with files opening up your browser to napster has been fixed. Get it here:

dazza2908,
If you download limewire from any place other than the official site you take your chances. That version could be hacked and contain viruses/adware/spyware ect.
