iPhoto 09 HELP not working OS X 10.6.1

[John Varela]

Recently upgraded to Snow Leopard and iLife 09. iPhoto 09 HELP will open, but clicking on anything produces a pulldown that says, "Help Viewer cannot open this content."

HELP works in other iLife apps and in iPhoto in other accounts, so the problem is specific to iPhoto and my account.

Someone reporting in an Apple forum said he had this problem and the AppleCare tech led him through deletion of several preferences and caches which solved the problem for him. He didn't write down exactly what steps were taken so couldn't advise how to repeat that solution.

I deleted the iPhoto and the Help plists but that did no good. I can't find the iPhoto caches.

Any suggestions?
