I'm having problems with the graphical end of Designer - i can create a form in designer, save it as a PDF, re-open it in illustrator and add nice vector graphics and have the saved form still work (just don't play with the form objects).
This works pretty nicely for one page forms - the problem comes when you have a a three or five page form. Illustrator can only open one page at a time. So you do each page and then reassemble the PDF in acrobat pro - NO the ability to insert pages into forms created in designer is disabled and i can't find a way around it - does anyone have any ideas?
