+    PSUTIL Desktop Widget
+    Creates a floating CPU utilization window that is always on top of other windows
+    You move it by grabbing anywhere on the window
+    Good example of how to do a non-blocking, polling program using PySimpleGUI
+    Use the spinner to adjust the number of seconds between readings of the CPU utilizaiton
+
+    NOTE - you will get a warning message printed when you exit using exit button.
+    It will look something like:
+            invalid command name "1616802625480StopMove"
