The cookie management part works OK, but somehow Flash video (Youtube etc) does not start playing; I have to ctrl-click, and select something from the popup, then go back to the Youtube page. When I drag the SafariPlus folder to the desktop, Flash is OK.
My combo:
OS X 10.4.11 (fully updated)
Safari 3.2.1
FlashPlayer 10
SafariPlus 1.6.A1
SafariPlus
