Thanks again, cybmole

That's an interesting possibility, the the books.db file would be different on each Sony since I have different ebooks on each reader - there is some overlap.

I think the only way to test the hypothesis would be to delete the books.db file on each reader, then start up the T1 before the others. I'm not that desperate yet.

I don't think the T1 uses the same firmware (or whatever it's called) as the T2 and T3. On my T1 left quotes point upward to the left, but on the T2 and T2 left quotes point upward to the right. And of course the T3 hyphenates, but the others don't.

PS Thanks for the link. I'll explore the forum in detail later tonight.
