Gtk2hs then complains about running in a multithreaded ghc, ie. one with several "real" OS threads. Is it possible to start runghc single-threaded?
No, but you can unsafeInitGUIForThreadedRTS.
If you observe the foot-shooting restrictions (of which the easiest is to not use forkIO).

And exactly herein lies the problem :) I've seen your response to the recent post about gui state, in which you mention your own prefered solution to the problem, ie. that you "post" your state to a channel which is read in a thread. I'm doing the same thing, but I'm also "calling" gui code from within that thread. I figured since the thread itself isn't a separate OS thread it shouldn't be a problem. It seems to work once the app is compiled, but running the code in either ghci or with runghc it crashes. Günther
