Find and highlight text in other app using regular expresion

[r0n]

Maybe I did something wrong or understood something wrong but I can get the colors to reset back to it's default in a QM richedit control. See below example:

As an alternative, is there a way to so set the full background color (highlighted text and rich-edit-field background) back to white?

Function re_highlight

Code:
