Lost Ability to Close All Tabs/slides

The dread of repairing or reinstalling led me to research a bit more and experiment with a few things.  

I discovered that if I swap the monitor arrangement, the functionality was restored on BOTH monitors.  I switched it back to my preferred setup...and the problem/bug returns.  

I believe this is an issue with Windows scaling somehow...and it still puzzles me how this only recently started happening.  

I appreciate your attention to this Jose, and I am not in any further need of assistance. 

I more hope that this information helps you and the Articulate Team if this becomes an issue for any others.  

Thanks again!
