I'm running Limewire Pro with Windows XP.
This has happened 3 times now, I know it's probably a simple solution, but here goes.

Limewire is open with a list of anywhere from 5 to 30 projects to be downloaded and uploading at least 5 projects.

Using Pirates Bay for my "search engine" I will click to download a file from them and I get the standard download message that it is saving to limewire.

Everything works great except sometimes a new window will open with another limewire (same version). This will include all of the files that I am working on in the first window. You can end the second program and go back to the first but the next time you try to download, a new window with another limewire will open. I've had 3 running which does increase my files that I can download, but it does tend to suck up systerm resources.

Restarting the system doesn't help.

It is sporadic in nature, so I cannot find a pattern.
