Hello Boxcar - I wanted to see framerates, because I am getting very smooth performance on this little Acer machine. However, it is an Acer, and their OEM Win7x64 includes a Hotkey Utility, which is fine, except that pressing Ctrl+F1 calls that, instead of the AFS2 frame rate etc display. So I went into Program Files (x86) and used the uninstaller. Ctrl+F1 now consistently toggles the AFS2 display.
The added info is in a small white font at the bottom left of the screen, which is fine - I don't need it all the time - but it does not show up in a screenshot. I have 'S' set as the screenshot key, and it picks up the info bar at the top, the Map if I have it open, and the Flight Review slider if it is on the screen. So I tried the old Win7 'Print Screen'. but nothing appeared when I opened Paint and tried to paste from the clipboard. Not a real problem, just posting this in case others have run into the same thing, while I have a closer look.
Nothing for anyone to lose sleep over
