Looks like I may have solved the problem. Font Book has been reporting duplicate fonts for Arial Rounded Bold, Courier New, Courier New Bold and Webdings when I check for duplicates for all fonts even though I've ran "resolve duplicates" many times and no duplicate warning triangles display in the tree view.

What I did was re-enable all the duplicates for those fonts, then I rebooted and resolved duplicates again and then rebooted once more. After that everything seemed to work ok. My guess is that an earlier Resolved Duplicates from before I had Snow Leopard resolved in favor of an older font and disabled a font that Webkit now requires. Anyway that trick appears to have worked for me and it's worth a try for anyone else experiencing problems with fonts related to Omniweb and Flash.

Thanks to everyone on the forums for their suggestions on how to fix my problem!
