What do you think is the uggly issue with Acrobat 9? I know the CS4 fotnt issue that displays correct in Acrobat 9 and incorrect in earlier versions, but that is not an Acrobat issue.
I upgraded to CS4 last winter. Our Studio still uses CS3. It happened twice so far that opening InDesign CS3 jobs in InDesign CS4 gave strange results. The last issue just happened yesterday with some text to path that was just fine in CS3 and got one line turned to mess in CS4 for no reason. See attachment.
