Difficult to describe this. When editing text (70% of the time), after hitting enter the display will show as if I'm still editing the text, but text entry is finished. The display is not updating past that point. I can select all by typing and delete and it works, but the graphics display doesn't update. This just started happening over the past week, possibly after a windows update. Also the cursor does not display in the graphics window but i can see it over other toolbars.

If I have 2 drawings open, I can move to 1 tab, then move back to the drawing and I have control again.
