I'm very happy with the upgrade to 1.5 (thanks GeffC!). Everything works, even the font size buttons. The delete button works. Paging at speed works very well indeed. I now have my books in folders according to authors. Ummm... am I missing anything out? Oh yeah - it hasn't frozen once since the upgrade.
Of course, now that I've posted this, everything will start to go wrong
