TOKEN  I have the same problem - no webaccess at all when adblock is enabled.  
(Version 0.3.1)

TOKEN  I think this is a very promising vector application - in comparison with its competitors it is more intuitive and has more funcionality that I can use.

It has a weakness on import/export formats. It only supports EPS import, no other formats.

But it is buggy..

TOKEN  This is the best bibliography app on the mac platform. Sente is a bit more elegant in the UI and has some cool features, but Bookends is much more mature and supports more formats with more details.  
(Version 9.0.4)

TOKEN  This app is eating my CPU for breakfast!! On my 1.33Ghz iBook it takes between 45-55 % of the CPU for itself!!

Apart from that Its a really delicious application that I would consider to pay for, given a few enhancements. For now its unusable.
