That's awesome, did not know you could do that, because I had always had the mouse option enabled. I see now how the onscreen pad can work with the -nomouse option in play. I was looking for the ui_mouse to takeover for that, but that's not the case.
Just for giggles, I digital photoed my toy's lamp and added that tile in with a few minor tweaks to the overall rendering. The zip file link is updated. It looks and feels like the real thing now, thank you!!
