My experience matches Jerry's. If it isn't bookmarks, something else is hogging resources. The browser is trying to pull too much through the pipe and getting things clogged up. Some process is going on that shouldn't be. Another thing to check: Safari had a problem for a while with RSS feeds. Check to see if it is trying to update dozens of RSS feeds without your knowing or wanting it. That happened to me once. Good luck. Peter
