Hi @David Berg
This issue occurs from time to time, there may be many possible factors.
Does it reproduced in other programs?
When it occurs, is there an attempt to change the touch mode, such as changing the mouse? It is recommended to try the following steps to have a check.
- Please go to File > Options > Add-ins > Manage COM Add-ins, click Go, clear the check boxes for any enabled COM add-ins, select OK.
- Make sure your Office is updated to the newest.
- Update the graphics card driver.
