Every time my mouse moves over the score it moves. I have to click in the navigator box to go back to the music, but again every time I move my mouse over the score it disappears again. There isn't a problem with my mouse and my computer is working fine. I have Windows 7 and I downloaded the 1.0 version. Also, when I try to click on any of the drop down menus (file, edit, create, etc.) the will not stay down. I have to drag my mouse to whatever I want to click otherwise the menu disappears just as quickly as I clicked on it. Please help!!! I have an assignment due by 11pm, which will most definitely be late at this point, but I do need this program to work.
