First, I'd like to thank you for the new version of Bookends, it's much better and faster than version 7, I think.
Second, I have noticed (in version 8) that whenever I have the cursor on a text field, there is a flikering of the cursor, as if it doesn't makes up its mind and starts changing very fast between the insertion point and the arrow. It happens only if there is already some text entered in the field and not when it's empty. Not really a terrible problem, just annoying. (Using OS 10.3.8)
