My undo/redo buttons are gray? can't undo anything when i make a mistake it means i have to start from the last time i saved.
also the "more instruments can be installed" popup pops up everytime, even though I click don't show this message again, as well as the "buy the next upgrade for79$" popup when I exit the program. Every time I have checked the dont show again box, to no avail. Tried clicking the x to exit the window, and closed it by pushing close. Neither work.
