It's possible to set specific modules to only be included in 32/64 bit builds via the properties pane. Is there something similar for specific windows? Can't find it, and can't add windows to modules.
windows are special in that regard
modules you can exclude this way
however IF you want a window stripped from a 32 bit build and you make sure you
then the compiler will find that the window is NEVER used and will strip that item from the built application
