Sorry to resurrect an older thread, but all of the threads on this issue don't end in a solution.
I have a Lunchbox/BigBox install on a Windows 11 machine that is constantly shutting down the computer. I first had LB installed locally, and the shut down would happen randomly anywhere from a few minutes to an hour in. No other program on the computer exhibits this behavior. Running emulators outside of LB works fine.
I recently made LB portable and installed it on a network drive. Launching LB/BB from other computers (2 Windows 10 machines and 1 other Windows 11 machine,) I haven't experienced the problem. The Windows 11 machine that I did the original install on still exhibits the problem whether I launch the local or network app.
Any help is appreciated!
