Have tried in vain to download 1.4.6 and after many crashes unstuffing etc. I still have version 1.4.4 as the downloaded version.
Does 1.4.6 exist and if so does it finally allow scroll wheels to move the pages and show in a screen size that is readable on a 20inch iMac. Not having to blow up to read would be handy. Yes I have also re started my printed version until such time as it is truly useable.
