I've noticed that, as well. Unfortunately, nearly all of the controls on the panels have Message Bar messages. Fortunately, they mirror the Tool Tip messages, and we don't have a HUGE number of panels. Just clearing the Message Bar messages may be the final answer on this.
I vaguely remember seeing reference to that somewhere in my past. I just tried a couple of tests, and while the timing seems good, we've also embedded some color highlights into the report listbox lines and these exports lose those. Will keep it in mind for future possibilities, though.
