Jul 14,2023Try holding the Shift key when you double-click to run LightBurn. One other thing to try: Press Ctrl+Shift+Esc to bring up the Windows task manager, and look to see if there’s a hung copy of LightBurn in the list. If there is, select it, right-click, and choose ‘End Task’. If there’s a copy already running, it will try to make that one active instead of running a new one, and if it’s hung, that won’t work.
