There are two possiblities:

1. Use threads (does Windows support stuff like that?)

2. Use your own event supplier. The PG_Application object uses an event
supplier (can be changed via SetEventSupplier()) to get the SDL events
that are waiting (See pgapplication.cpp; start at PG_Application::Run()
with reading). By deriving your own supplier and having the application
ovject use an instance of it, you can insert your own code into the
event handling chain. (Though I have to admit that I have not used it so
far, so I cannot give you mroe help here for now).


good luck, 
Ulf
