Great app but...

For some reason, when I try to open an epub or mobi sent by mail, I cant get Total reader to open it. No problem with oter reader apps.
A pity, because I really like the
many settings the text, choice of fonts etc.
If it was not for the bug I mention before, this would be my favorite reader app.
