This version of Create has a new Menu item that works with PStill:
1. First, make sure you have added Create links to your document - either ones that link to another page, or to external links. HINT: if you are copying text from Safari, use the mouse-down/hold a second/drag the text clipping from Safari to save the embedded links [the document you sent me did not have valid links - you can check by selecting the link and seeing if it appears in the Info -> Web panel.
2. Then, choose File -> Save Other -> Save PDF w/ Links in PStill
That's all! Create makes a slang script file, installs it in PStill, set PStill to use that file, stops and relaunchs PStill, saves the document as PDF, and asks PStill to reprocess it with the Clickable Links embedded - you may have to view the PDF with Acrobat to actually get the clickable links to work though.
Be sure you remember to set PStill's Preferences -> Output Options, Control Script popup back to "1-up" before you do other processing, or you'll end up adding links to the next PDF you process...
