It’s great that 3.02 now allows me to import .zrtf files created by Nisus Writer Pro.
If the Nisus file contains an image however the import just displays garbage where the image should be, and everything afterwards is blank.
I guess the fact that DT3 cannot display the image properly is a known limitation.
However the fact that everything below the image is blank is probably a bug?
In my case all the letters I imported contain my company’s logo in the header, and hence they are all completely blank in DT3.
