Hi, After losts of surfing in Google and in wxHaskell Haddock documentation I find out this possible solution that works fine for my case
wxcAppYield (http://wxhaskell.sourceforge.net/doc/Graphics.UI.WXCore.WxcClassesMZ.html#v %3AwxcAppYield ) or its variant wxcAppSafeYield (http://wxhaskell.sourceforge.net/doc/Graphics.UI.WXCore.WxcClassesMZ.html#v %3AwxcAppSafeYield ) It is simple as calling this function before testing if a certain button had been pressed and its call-back had update the state of the application accordingly. Thanks for your help. Best Miguel Vilaça -----Mensagem original----- De: Eric Y.

Does calling wxcAppSafeYield in your long computation (look in the index of the API) help? I don't actually know the answer, just making some guesses. You might want to look into what Dazzle/XTC do, otherwise. And if it does help, maybe you could write something up on the Haskell wiki so that other programmers won't have to suffer!
