Total Commander

The parameter HorizontalLines is missing in the Help file.

Since it is actually working for both Dark Mode and Normal mode ( https://ghisler.ch/board/viewtopic.php?p=433284#p433284 ), I suggest that it is documented in the [Colors] section and not in the [ColorsDark] section.

I also suggest that it is put by itself in the Color settings dialog - like here: https://tcmd.madsenworld.dk/horizontallines.png instead of in the "Dark mode:" section, so it can be set via the GUI for both Normal and Dark Mode.

It's not working 100% here in normal mode, so I will keep it undocumented.

What is the problem in normal mode for you?

On Windows 11, the line between menu and button bar reverts to the theme color in some cases in 32-bit. It works fine in 64-bit.
I couldn't find the reason, I handle all the WM_NCCREATE, WM_NCPAINT, WM_NCACTIVATE message, but it still happens.

I will document it for the [ColorsDark] section for now.

Description confirmed added to the Help file in TC 11.00b7

I would still lik to see this implemented in the GUI for Normal mode too - so could this Topic be moved to the Suggestions forum.

I can say that here (Windows 7 and 10) the theme line (double line in Windows 7, single line in Windows 10) under the Menu in 32bit TC only is visible when "Flat icons" is selected for the buttonbar: https://tcmd.madsenworld.dk/horizontallines32bitflaticons.png

With "Flat icons" disabled for the buttonbar I only see 1 line under the Menu in Windows 7, and no line in Windows 10 https://tcmd.madsenworld.dk/horizontallines32bitnonflaticons.png - the same as I se with "Flat icons" enabled after taking focus away from TC.

So the "Flat icons" setting seems to play a role - maybe that can help you figure out to fix it for 32bit TC.

On Windows 11 it misbehaves also when "Flat icons" isn't selected.

OK, no hope there
