SolidWorks wont fill laptop screen, missing right and bottom sections.

SolidWorks wont fill laptop screen, missing right and bottom sections.   Missing about 10% of right and bottom parts of screen, including standard windows selections to min, full or X-out of screen.   Otherwise SW works fine.   View then "Full Screen" in SW "works" but overall SW is still missing about 10% of right and bottom screen.   All other programs, websites, etc still work just fine and normal.   I was using this Laptop with external screen including Extend Screen across laptop and external screen, with external screen to the left.   I haven't yet tried plugging laptop back into additional external screen, which I'm guessing will somehow let me fix this, but I'm still wondering if there is some easy fix, and is this a SW issue or something else.   Tried restarting laptop a few times, Esc, etc.   Seems only SW is doing this.  I can reduce SW to nothing by dragging from top or left.  Picture shows the max it will display to top or left side, and how it will initially display.
