I'm running Windows 7 and have had absolutely no issues with this program. I too have used WordPerfect back in the 80's and 90's and was so disappointed when it disappeared. I have always wondered why other programs don't use "reveal codes" as it makes...
So far, about the only con I can see is that it doesn't have the tool Water Mark I have always used on my business cards. Maybe I'll find it somewhere... Hope so
