@AM: trust me, the FRIdNGE solution is amazing. We do the layout of legal docs in 2 languages in 2 “frames” and Michel helps us to speed up the process. As he said, just one click to align both languages (ex. 40 pages in 30 secs).

Maybe this can help

Tried pdf/x4?

Leslie, sorry to say this, but I think it’s time to let go of PageMaker and restart from scratch in Indesign. I too had to make the switch for all of our publications, some were easy others not. It took us a lot of time, and some programming was required to get things done. The lack of “detailled find and changes” in PM were solved in Indesign, but this means indeed that “simple changes in PageMaker” are no longer working. You’ll see, once you get the Indesign file right, it will be a lot easier…

As far as I know, you can export to ODT and then import it into Indesign (formatting will not be good).

Try the new gwg2015 settings and pdf/x4. The profile TAC220 can still be used.

Could be a cache problem on the laptop. Close Indesign and look for the cache folder and rename it (so a new cache is created). Try opening the file again.
