Bob, thanks for investigating this further. I have had the problem in both 11.6 and 11.7 . I have been using mainly Firefox, since I have been doing a lot of debugging in general. This evening I "hammered" my web page (meaning many reloads of applet data, scrolling, browser resize) in both safari 3.2.1 and firefox 3.0.8 on a laptop running leopard 10,5,6 . This time three of the six applets on the page froze in safari, after switching context from firefox. I was not able to get any freezes in firefox, although on occasion I need to scroll the page a bit to prompt all the applets to load.
