ListView setting $LVS_EX_FLATSB flattens header only instead of scrollbars

[sys55@…]

Bug in AutoIt Version: 3.2.12.1

ListView setting $LVS_EX_FLATSB flattens header only instead of scrollbars

ListView Control with $LVS_EX_FLATSB set does not flatten the scrollbars. The header though gets flattened, something not wished.
See attached file for a demo.

Running XP professional SP3, classic Windows theme.

This is not a bug. Flat scrollbars are not supported when using comctl32.dll 6.00 which is what AutoIt uses on Windows XP.
