Yes, the mouse pointer. The actual arrow mouse pointer is normal size, cross hairs are fine, it is only when I select an object on the plan (like a wall) and hover over one of the indicators to move it or resize it and the mouse pointer changes to the "double headed arrow" or if I want to rotate something and the pointer changes to the circle. At those times the mouse pointer is so small it is almost invisible.
My triangle indicators were super tiny at first also but I had no problem increasing the size of them (just changed pixel size).
