Mouse pointer disappears on parts of the screen

I have recently updated to Draftsight for Mac 2023 SP2 and noticed my mouse pointer disappears on parts of the screen. It woks in the main drawing area (cross hairs) but disappears when I move across toolbars. If I can manage to float over the right area, the click brings up the right button or other function, I just cant see the pointer. I am using a MacMini and MacOS Ventura 13.4.1. I have rebooted a few times but this has not fixed. Any ideas?
