Hello all!
I own an HP50G. I often get 'STUCK" on a screen and I cannot go back to the main menu or cancel. Example: I want to produce a graph, after I see the graph, I want to produce another one, I cannot go back to the menu to change the function. The thing keeps beeping at me. How can I do that and also how can I navigate, that is, go around and always be able to get back to some basic manu?
