Ugs platform issue

hi
I have noticed shapes on the main screen of the ugs platform.ugs
I have deleted the program then reinstalled it and got the same image as seen in the enclosed picture. The program has been used previously without the shapes appearing,
Any thoughts?
thanks
Larry

Larry, did you try clearing your cache directory. It’s location can be found listed in the “About/Help” window?

I looks like the dowel maker tab is open. If you close it they should go away.
