OK..here's what's happening...I just created the drawer pull in a tutorial I'm working thru and "made a component" and "saved". When I went back after saving and went to do something, it didn't do anything. I could pick the box tool, but when I made a box shape, nothing appeared. I then grabbed the circle tool and made a circle, but nothing appeared. I could click on a different layer and that layer button would get a "on" botton black dot, but nothing on that layer could be seen. So I hit the "X" to close Sketchup and it asked if I wanted to save...I said yes, and it quit out. When I opened sketchup again, the box and circle I made but didn't see were there and the layer I clicked on was now on and I could see what is on that layer. What's goin' on???
