weird happenings
 

get shadow like effect when click on drop downs and then release, drop down menu leaves "impression" on screen that does not go away. 5 min may pass and little "ghost" box of previously used pull down menu still on screen blocking out what should have re-appeared as soon as i let go of drop down menu.

also, my library will not appear in alphabetical order, even though i go to the main folder and auto arrange by name and they are alphabetical there?

any ideas on my two issues?

P.S. 2.7.3 is a CPU hog
