I have a question about Safari plugins. I was running under Tiger and got the SplashID desktop program with Safari plugin. Worked beautifully. I decided to upgrade my OS to Leopard so I can use a newly purchased Magic Mouse. Launched Safari and the SplashID plugin would not load. I replaced Safari, its preferences and other files and the plugin will not load. It worked fine in Tiger. I happened to have another internal drive loaded with Leopard from a while back and it's fully updated. I booted from it and installed SplashID and the plugin. Works perfectly! So, why will the Safari plugin not load on my primary drive that was upgraded from Tiger to Leopard versus the same Leopard on my other drive that was a clean install?
