Nice to see you again here!
oxen, I already pointed out, in post # 43, 45 and 47 my problem with ES and of course things have not changed because I didn't try the last update, simply because I have a bunch of apps to fulfill my goals with epub. So please, don't take it to personal, I was not bashing your app and this is not a negative judgment about the new version of ES.
If I can find a solution for .NET, I'll give a fresh start to ES.
BTW are you working to a way to add more files format, maybe odt?
Have a nice day oxen!
