Hi

Tapping the centre of the screen does not bring up the header and footer - they are already there but with a blank screen. A single tap does not necessarily bring up the text. The way this is done is that I have to long press on a blank screen so that it brings up a dictionary definition (so I suppose it is a bit hit and miss as you have to be selecting an 'invisible' word). Once the dictionary window appears and is then dismissed, the book text appears.

As regards your possible solution re embedded fonts, I have already side loaded in a font which is being used.

I have not edited the books as far as I am aware. Shouldn't a factory reset and reload from Calbre have avoided the potential metadata/toc issue? However something strange is going on because at the end of a chapter last night the device opened the previous rather than the next chapter!

Additionally after loading a font for a particular book I was surprised to learn that the original Georgia font was still being used for another. Is this how it should work i.e on a book by book basis rather than globally?

Many thanks for your assistance with my issues.
