PsCC, Rectangular Marquee Tool "marching ants" disappear when Left CLICKING

Creative Cloud just "updated"  all my Br/PsCC apps to latest version. Now all sorts of technical issues are being presented! Brushes don't work as used for 25+years, none of the Tools works correctly. Case in point when outling an image with the Retangular Marque Toll, after the box is created, creeping ants are shown, I right Click to FILL and the box disappears! When I release the trackball key the MT selection re-appears!

Also when the im age is "SAVED" and you see the thumbnail in Bridge, the red arrow is NOT show yet when Click and Open it is THERE!!

Windows 10..62Ram, all previous versions ran fine!
