The Highlight/Annotation only sometimes works. Often only a single word selected and then it seems to freeze.
I thought at first maybe it was a nearly dead battery, but the stripey symbol means fully charged and mostly it's fine simply reading.
I've done a Factory reset (previous owner simply deleted files). Updated from 1.0.03.11140 to 1.0.07.05070 using a Win7 PC, stupid that it's a Windows self-extrator exe that then runs a windows program.
I thought it was crashing / freezing most times on trying to highlight and add note, but if you wait for about a minute it recovers.
I'm also thinking it isn't recognised
as a T1 in Calibre, but as an older reader.
