Cool combination.
The PB editor (6.02 LTS) is fine at first launch.
After restarting windows some problems appear:
- The opened files tabs appear black on black, can't read the names anymore, although the tab is correctly white on black when creating a new file, until you type the first character.
- The "live hint" at the bottom is only readable when the cursor is outside the function's brackets. I guess it's black on black otherwise.

Some years ago I had the same trouble with the "live hint" on winXP when using a personal dark theme.
The manual looks good in the high-contrast mode, with a minor bug: when searching for a word, the search works but the occurrences are not highlighted, although text selection by mouse still highlights the selection in teal blue.
Thanks and good luck.
