I recently completed a project that was built from a previous program (started with Version 4 program). Somewhere along the way, an ISO lamp image became invisible. I'm not sure how it happened, but the only way to fix it was to add the same lamp image (same size and color), delete the old one, then use the 'undo' command. When the lamp image came back on the screen, it was correct and visible. I'm not sure how this could have happened, since this area of the screen and all related channels were unchanged from previous program.
