It only shows for a fraction of a second, and I haven't been able to catch it. I tryed opening creo a few times to get a good idea of what I see in that moment: in the tray along the bottom of the screen it momentarily shows a window called "Message," the approx 1 inch window has the header "message," there's a white exclamation point in a orange safety triangle at the left top of the box, right top says "message," and across the bottom it has an "okay" button. I'm not hitting anything that would select the okay, it just goes away.
