I'm a Mac user. I am using Safari (IE not available for OS X) with the Adventure Tools. I am trying to Save as a PDF the monster I created using the Adventure Tools. I click Save as PDF, and then "OK" and then nothing happens. Here's a Screen Shot (see attached). Anyone know a work-around? I guess I could Screen-cap and then crop the image. That's a PITA, though, and the text wouldn't be selectable. So... not an ideal solution.
I had this issue, too, after upgrading to Mavericks and the latest Safari. However, if you use FireFox, you should be able to save as PDF. Hope this helps.
