Hi, Can someone tell me how another way then gtk-standalone-main to launch a gui in guile? this kills the development environment when quitting the app ... (a terrible thing, when you have 15 modules including postres connection ... and just the latest that you work on ...) Attached is a very simple example that uses gtk-standalone-main: what should I do to avoid it (but be abble to 'launch' the gui of course), getting error display messages in the guile listener and above all, not loosing the environment, whether the gui is bugged, or whether I use the quit menu ... thanks, david test-debug.scm
