Hi, I have got Arbort text 5.3 newly installed im My machine. Previously I used to work on Arbort text 5.1. I am unable to view the documents correctlty in 5.3, Wherer as the same file is opening in 5.1 without showing any error message. What might be problem? I have analysed few points: 1. DTD compilation problem in 5.3. 2. Unable to generate the Print Preview , Not reading stylesheet FOSI correclty. Same SGML file I am able to view in 5.1 correctly. Are there any settings needs to be changed in 5.3? Please let me know. This is very Urgent. thank You.
