Different Computers Different Results

[tpk555]

I have Limewire on 2 computers. I have checked all the settings and options and they are set identically on both computers.
The problem is this:
Say I do a search on Sarah McLachlan for example.
On one computer, the one running Win XP, I may have 205 results. However, on the other computer running Windows Vista, I only get 95 results. The one running Vista has the newest and most recent version of Limewire.
I have no clue if the OS actually has anything to do with this. I point it out only because I'm wondering if it does. Again, all options are set the same.
Thank You for any help or suggestions you can offer.
