Ok, I will stop worrying about the winamp.ini file. Mine is only 14KB and deleting things has a better chance of hurting something than helping anything.
I am using the settings cache option on the preferences advanced page 1. The note to disable if 3rd party plug-ins don't work properly gave me pause, but I enabled it anyway. All plug-ins listed with the WACUP icon, I no longer consider to be 3rd party, even if they started out that way.
