The RadLab Automation panel provides a convenient way to launch RadLab, and to place the result in a new layer or smart object. For some users, the automation panel is unstable or behaves erratically. Since RadLab is no longer a supported product, we can't make any changes to the automation panel itself.
Instead, here's a small set of Photoshop Actions that performs the same tasks as the RadLab Panel. You can install these and access them via the Actions Palette.
