I use 10.4, and downloaded this application as I need to download and fill in lots of pdf forms, then post them on by snail mail as part of my work.
After just 10 minutes use I'd paid the developer.
It's easy to use, quick, and foolproof. (It must be, I use it).
Can't understand the carping on about the price - I've evaluated at least two more apps that cost $20 more that aren't as intuitive.I had one query and it was answered within 10 minutes..... That's support.
