The 1995 FB2 handbook enjoins us (page 55) not to use more than one event loop in a program. Why? So far as program logic is concerned there should be no trouble as long as the loops do not interfere and the FN doDialog s are redefined in appropriate places. It would be useful to have several event loops in one program, for example when combining several different programs, each with its own event loop into one. Am I missing something?
