you start it once and then it's running. You should not sleep since that
would block the main loop. Instead you should hook your functionality
into the main loop.

gtk_signal_handler_block()
gtk_signal_handler_block_by_func()
gtk_signal_handler_block_by_data()

gtk_signal_handler_unblock()
gtk_signal_handler_unblock_by_func()
gtk_signal_handler_unblock_by_data()


Salut, Sven
