I just noticed this.
But scrolling around with the navigator the map (smaller image, with the bigger view) doesn't always sync with what is showing on the screen.
A lot of piccies to show the problem.
I have tried to show as best I can without writing all over the screen. (That doesn't help)
And I save the piccies as PNG not JPG.
I've put a red box around the navigator's what you are looking at and pointed to the scroll (vertical) bar of the window.
Though they sort of line up, there are times when I am looking at a blank screen and the navigator says I should be looking at code.
fan node I have shows up as dark green and in a couple of cases I point to it on the navigator window and where it is really (sometimes off the screen.)
I hope this is helpful.
