Frozen screen. My computer just beeps at me when I attempt a command. I can not close, save or do anything on the project. I can open other windows including internet browser and start button features, but the excel project is stuck. Can I recover the project if I do a hard reboot? I have attempted unplugging all of the USB connections from the computer including mouse and keyboard, but I'm still not getting anything from the frozen project. I'd hate to lose the project. Any thoughts/help would be appreciated. Thank you!
