[BetterRed]

Say I want to select a sentence or two, in the viewer, to copy and paste somewhere. I select the first (or last word) with double click, then :

sometimes I can extend the selection either to the following words via Shift+Ctrl+right, OR to the preceding words via Shift+Ctrl+left

but at other times I can only extend the selection to following words, but not preceding words - and sometimes it's vice-versa

And at other times I cannot extend the selection in either direction

I can't find a pattern - it's not particular books, all three behaviours can occur on the same paragraph on the same epub. Reloading does not have any effect, nor closing does calibre and emptying its cache folder.

NB: Extending the selection via the keyboard didn't work at all on the old viewer, which makes me wonder if it is intended to work with the new viewer. It doesn't work at all in the 4.1 Editor Preview - but its never worked there either.

FWIW: extending selection via the keyboard works perfectly in Sigil's Preview and PageEdit .
