Command-H to hide front window
Command-H has always hidden the front window. Now with a brand new i9 iMac 10.15.2 and the accompanying Apple Wireless Keyboard with Numeric Keypad the key-command no longer works as it used to. Command-H will close/hide open windows one at a time, but not the last one. My intention is to close windows leaving only the desktop as was previously possible. Thoughts on why this is happening and how to regain the close-the-last-window capability?
