I'm having an issue with my SolidWorks 2019 SP5.

When I try to delete anything from the feature tree (feature, sketch, part, etc.) I do not see the delete confirmation dialogue box.  But it's still there, somewhere.  I have to press the enter key to proceed.  Clicking anywhere on the SolidWorks window will make the "ding" sound you get from not clicking on the dialogue box.

I do not see any new windows popped up on the Windows task bar, or by pressing alt-tab to see the available windows.

It's not  a result of hiding the delete confirmation.  It's still waiting for me to confirm the delete, but that window is not visible.

Any help would be appreciated!
