MDI applications have multiple message pumps, but only one thread. As a
general rule a windows application should only have one thread that handles
keyboard/mouse input and display output. Additional threads are usually
only used when processing time would impact the responsiveness of the single
user interface thread. Cor is absolutely correct in stating that too much
threading is bad for an application - remember that each thread involves
system overhead for scheduling and resource management as well as generally
increased complexity in the application itself.
