Hello Kovid
I am hoping you can help me. I have some Sony Store purchases which are epubs and I have just figured out how to 'liberate' them

Got them into Calibre no problem and onto the reader, but the font was tiny. So I converted it in Calibre into LRF as I prefer those to epub, and the font was still tiny. So I tried to use the font zoomer on the Sony and it crashed every time. The whole reader shut down and I had to turn it back on, then there was a boot-up screen with the Sony logo, then it returned me to what I had been reading before I opened up the problem book. This happened more than one time. It was all good until I tried to zoom.
So I deleted the LRF and have reloaded the epub onto the Sony. It's fine now. The font is still tiny, but I was able to use the zoom and nothing crashed. However, I still do prefer the way the LRF looks and would like to see if there is a fix. Any suggestions for what may be going on?
