Hello all. I am using a Powerbook G4 15" 1.33 GHz. Just recently (within the past couple weeks) I have been noticing fewer and fewer applications that require networks to run simply won't work at all anymore. So far the following have happened: -My IRC client won't let me login -None of the FTP apps I use will let me login -iTunes won't show shared music on any network anymore -Various other file sharing apps (whose names I won't mention) won't even launch at all When I do attempt to use these problem apps, little or nothing happens. If they start to launch, they bounce once in the dock then disappear or won't let me login. I have tried virtually everything I can think of. I have reinstalled all of the problem apps; I've verified and repaired my permissions; I have connected to numerous different networks (including my university's) and still the problems persist. I have been considering deleting network .plist files, but I'm not sure which ones are safe to delete or even relevant for that matter. IRC and file sharing, I guess I can live without, but I need my FTP programs to do my web design work. Is there a way to reset my network settings to the factory defaults? I can't afford to do an entire system restore at this point, so I'm hoping someone here can point me in the right direction. PLEEEASE. Thanks.
