I have now got my 7in touchscreen installed for use with RA+Re6 and it seems to work well. I have found the Screen Off option on the Features / Browser on RPi page and it does what I want, acting as a screen saver. Unfortunately on the same page, the Zoom option is not being saved. I am trying to set it to 0.7 (or '.7' as we used to have to do in earlier versions) but this value is not saved and it is reset to '1' whenever the screen is refreshed.
Regards.
