This is the first report of this if I remember correctly. I see Ruida listed, running on which OS and what version of LightBurn are you using? For clarity, are you just moving the mouse, or is there any clicking involved as well?
We did have an issue using the Space-Bar to wake the computer.
Under the right conditions, the ‘Edit Window’ (workspace) doesn’t have focus, and the ‘Start’ button does, pressing ‘Space-bar’ could trigger the ‘Start’ button to fire. We added a switch in the ‘Settings’ under the ‘File Settings’ section to ‘Ignore ‘Start’ button if monitor is off / asleep’.
