That is a good thought, but I don't think that is the problem. I have a
double click event handler on one of my widgets, and it's not even getting
called. I would think that sending a double click event would cause the
double click event handler to be called, so that's why I think that
somehow I'm not sending the double click event correctly or somehow it
isn't getting to the appropriate widget... Thanks.
