To start off with we’d like to say that we’re aware that the PDF Creator does not work on Windows Vista. It’s a known issue that the authors are trying their best to overcome. We’re hoping to hear good things from that project shortly.
There’s also a new version out of Paint.Net that we’ll include in our next release. Progress marches on.
Some good news from our initial release is that there’s been great feedback from a couple of forums that will lead to ongoing improvements in the project. You can read and contribute to the ongoing conversations Here and Here. If anyone has ideas for other forums, blogs, or elsewhere (anywhere, really!) that we could spread the word, feel free to let us know.
