My e-book is DRM protected. I can not copy paste any text. Which is fine because it is a study book and you have added a highlight function for me to help me get to the core of the contents.
The highlighting function works. Sometimes. Yesterday I highlighted away. Today, I continu in the same document and the Highlight option is greyed out. CTRL+M does nothing. So I scroll to previous pages. Also there the option is greyed out. But CTRL+M does highlight a text. I don't get this random behaviour?!? I would like to hear a solution promptly.
Update: restarted the program and now I am able to Highlight. Still needs to be fixed though.
The problem still persist. I can see multiple users have this issue. Has this issue been added to your "to do" list? I have had no reaction.
