keeps closing


Is it because I got the free version that it closes on me almost every time I choose a topic? If that's the case, you should let the consumer know which apps are available and which are not. It was so annoying to have to open the app over and over just to try and find a topic that worked that I just deleted the app. It might be a great app and worth the money to purchase the full version but the free one was so frustrating that I don't want to give him my money.

Not free anymore


You have to get the paid version, can't believe he would do such a thing without letting us know... I don't mind that he would charge; for if you don't want to pay go and get it online and just do a print screen and keep it on hand. I got the paid app and all the notes work fine...

Latest update causes a CTD


Latest update causes a crash to desktop when you open up specific notes in every category (that I randomly tried). Don't these things get tested before the patches are released?

I already tried to re-install fresh and the problem remains.
