aspect ratio not set correctly
When changing (VIDEO PROPERTIES> Set Display Ratio) in outputted file, the original displays are all that's outputted.
Example: 4:3 Master changed to 16/9 in outputted file. Results = 4/3 display still!!!
When editing PROPERTIES... when a user hits tab to jump to next field for editing... the page scroll ALWAYS TO THE RIGHT!!! This never happened in older versions!!!
Example: Loaded MKV file, disabled all items in Tracks, Chapters and Tags, selected and highlighted only the files I wanted to use... I go to the PROPERTIES Box, I enter ENGLISH for Track Names, I hit Tab to jump in the next section (which I would then begin to select ENGLISH LANGUAGE) but the page scrolls to the right single every time!!! This didn't happen in v38, but appeared in v39.
Glad to see you fixed the dark coloring to reflect BLACK over BLUEISH-BLACK...
Also, v39 didn't retain any of the users previous settings!!!
Still testing for bugs...
