I have had RB minimised whilst doing something else and have noticed that due to it being minimised the FTP screenshot is blank.
After maximising the screen again and waiting 5 mins the image reappears.
See attached.

Simlar problem here. FTP is uploading whatever is on screen, rather than the Radarbox window. So, for example, if I'm looking at a web page, it's the web page that gets uploaded, not the Radarbox screen.

Ooooh! That could be embarrassing :-)
This one is corrected now.
