Notessimo won't let me compose

[Sorry for repost]
No one will read/respond to the help Forum so I had to post here
I have this bug that doesn’t allow me to compose,
When I open the window it works fine, I can place and delete
Then I test the song
After that, I can’t move, delete, edit or do anything to the notes
Does anyone know why?
It only happens on my computer

Graphics: Radeon HD 6450
Processor: Phenom II
RAM: 4GB
Monitor: HP L1908w

Before you say “Wrong Forum” It’s General and Help forum is dead.

Wrong forum, be patient next time. It’s only been two hours and that does not give you the right to go against the rules. Next warning will grant you a warning point.

Why is it against the rules to repost??? And this is a shout out to comodo records I hear you I posted stuff in general: of topic and people tell me that it is the wrong forum!!!

Why is this not locked?

Do it yourself Slippy, jfc.
