in Settings --> File types --> File types groups
adding an colour for e.g. EXE extension (here in RED)
That displays right in DO, all *.EXE are colored.
Not defined file types are black. Right.
Selecting (not defined) filetypes gives me a light-red row (right!)
Selecting (a defined) filtype gives me a dotted line row
- not a highlighting ----Why
Look at Preferences / Display / Colors & Fonts.
Sorry - did that - doesn't work...
Down I made a snapshot
Look at line dopus.exe
What colours did you set for the selected .exe files in the file type editor?
Looks like you gave them red text and a transparent background.
I did not make anything transparent, but made that error:
File types --> file colors --> selected background color
Prefs --> Colors & Fonts --> files --> selected background color
were the same
