Sure, that all makes sense. Good to know it hasn't been abandoned. I didn't realize that the viewport area would be defined by portions of the application window that are not actually inside the drawing area. 

I guess the other option would be to only use a mac :)

thanks though, please keep it up!
What's up with this? Any word? I'd expect the #1 priority from two years ago would be implemented by now, eh? :)
