Re: Application Gui doesn't become visible

[Eric Wasylishen]

Hi,
The windows theme is probably turned on, which gets rid of floating NeXT-style 
menus and displays them inside windows. You could either create an NSWindow in 
applicationWillFinishLaunching and call orderFront: on it, or setting the theme 
to the default NeXT style which will allow floating menus to show up (open the 
mingw shell and type: defaults write NSGlobalDomain GSTheme "")
