I'm having a similar problem. My search results look like this: Pet Deet (0/214) Porter Sellars (0/243) Wet Puppy (0/33), -etc. Zero available for download.

Running OS-X10.3 on an old 400Mhz Blue Mac, and basic (obsolete) LW. As an old school Mac geek, I thought I could maybe reinstall the Ap., and delete my prefs. Not true. Unfortunately, OSX isn't nearly as friendly as OS9 was for experimenting with extensions, etc.
