Hello Mathgroup, This is a question about frozen frontend behavior. In development stages, one of my frequent mistakes is to send the frontend something that takes forever to dynamically update---at least that is what I believe what is happening for most of the "freezing" occurrences. For MacOs, this is often signaled by a "Formatting Notebook Contents" window. I wonder if anyone has found a method to send the front end a message to stop dynamically updating while in an unresponsive state? I've various versions of kill -s signal (i.e., signal = INT) from a terminal in MacOSx, but never with success. I suppose that having the front end query the operating system for interrupt requests would create a lot of overhead. However, I wonder if a method to force the frontend to make an operating system query with a user-specified time interval might be possible? W Craig Carter
