Hello ,my Name ist Mario from Germany. I have a Problem. Ortur Lasermaster 3 with lightburn. When i create a Job. The Help window start Independent and open Firefox until PC Crash. I have the Trial Version .can someone Help me. Sorry für my Bad english.
Hi Mario, May I ask where you got your LightBurn version from? Could it be a version that is not an original version?
I have load It from the lightburn Homepage. A new Install dont Help. The Same mistake. Firefox Open x Windows with lightburn online Help.
Is the F1 key on your keyboard jammed down?
With a tool selected in LightBurn, pressing F1 activates the online help, so a little grit (*) would do that “automatically”. This is particularly easy to do in a laptop keyboard.
Source: Been there, done that. 
(*) It’s called “board chow”.
No , the F1 Key ist not down. I will now Install win 10 new and Download lightburn.
Win 10 ist new installed.lightburn also. First Picture burn - No Problem. But when i exchange the Speed in the Cut window with the Keyboard ,start the Help window and Firefox. When i exchange the Speed with the mouse ,No Problem.
Does this latest test include trying a different keyboard? I know this is not very comforting, but you are the first to report this behavior. My first thought is similar to @ednisley, something happening with the keyboard itself, triggering the F1 key which could invoke the help system to pop open your default browser and take you to our docs.
Please describe the exact steps you take to produce this. I am not currently able to reproduce this behavior. Your exact sequence may help me duplicate. 
Hello , It was the F1 Key . I have lift Up the Key from the Keyboard. And the Problem is gone. Thanks all for the Help.
Gonna laser-cut another notch in my lipstick case for this one!
Honestly that was an incredibly observant bit of insight. Well done.
