Miracle of Miracles, Initially, I thought my Mystery Beeps had disappeared due to the new beta, but on reflexion I realized I had made one other change. I was using Modal Windows, but in the doDialog Events I had - I haven't the remotest idea why - explicitly indicated that when ANY window was activated, that the Main Window would be shown. A real interesting dichotomy that caused FB to hiccup. For some reason I was never able to trace it through with the Debugger. Something totally different had led me to remove the doDialog event.
