I tried Foxit reader a bit but then I saw a popup if I wanted to use the function you need to buy Foxit Reader pro version.
This shouts to me this is nothing more than a shareware application as it shows features that can not be used fully.
Don't get me wrong, I like freeware, but this seems more like commercial freeware. While from a company viewpoint of PA.c it's good, from a user perspective it seems the application list becomes 'polluted' with applications that do have their drawbacks.
The suggested open source listing is still not there and clicking on the Open Source /Freeware links brings up a wikipedia page.
