Hilary, here is the information on the CoolReader version I use. Go to
http://sourceforge.net/projects/cren...r3/cr3-3.0.45/ then select cr3.0.45-11.apk and download it - I download to my PC. Use ES File Explorer to see it, when you have found it a long press should bring up the install dialog, install it and it will appear with all your other apps. You can then copy it to you home screen for convenience.
So far it has displayed everything I've asked of it.
To comment on why not being able to use the latest apps is good security for us. The script kiddies are not interested in using old things, they only thing about the latest and greatest so they are not going to even try and mess with older apps.
