Hello,

Recently, I faced a issue an error message did not display on the screen, but I could fix it by changing the below setting.

Harness form -> Advanced tab -> Harness usage -> Work area(to true)

I referred help about this option, however, help does not describe this option.

So, could anyone please share the information about this option and how to use it ?

Also, I found the below post, but it seems help has not been updated yet, even in latest version.
