What's up, Luckychunk?!?!
I think I've run in to that type of problem as well, it wasn't with Internet links but a certain filetype which had nothing to do with NSM would launch the NSM installer. I never figured out what was causing this but my solution was to uninstall NSM and use
NDBM to manage the music on my Neuros. I'm much more satisfied with NDBM than I ever was with NSM. You can download it here:
http://neurosdbm.sourceforge.net/FYI: NSM runs on the .NET Framework (not Java) and NDBM is a Java app. Your version of the JRE should run NDBM just fine.
FYII: I KNOW WHERE YOU LIVE!
