Total Commander

Here on Vista 32-bit with classic theme, in Total Commander 9.50 beta versions up to 5, Total Commander main window title system context menu was partially black when TC was in Dark Mode:
* if it was called by Alt+Space, it was all black except "Minimize" menu item which used system colors;
* if it was called by right mouse button click, "Minimize" and "Close Alt+F4" items weren't black.
Also, black theme disappeared from particular menu items if to:
* move mouse pointer mouse over some menu item and then move pointer out of it;
* switch to some menu item using keyboard up/down arrow keys, and then to switch to next item the same way.

Since TC 9.50 beta 6, after following change:

15.11.19 Fixed: Dark mode: The system menu (Alt+Space) had white background with dark borders (32/64)

TC window title context menu is not dark here at all anymore.

Even though the dark mode wasn't flawless in that system context menu, I think was better than current completely not dark menu.

Unfortunately menus are a big problem even on the latest Windows 10 version:
Windows 10 1803 and older:
1. System-drawn menus cannot be changed to dark mode
Windows 10 1809 and newer:
1. System-drawn menus will be dark when dark mode is set at program start, and they stay dark even if you switch to light mode later
2. System-drawn menus will be light when normal mode is set at program start, and they stay light even if you switch to dark mode later

The mishmash you saw in beta 5 is even worse than an all-light system menu, so I prefer to use it as it is now. Only when using classic theme it was as you describe it - when using the regular theme, it was just light with a dark border.

In TC 9.50 RC2 on Vista 32-bit with classic theme title context menu of TC (and now also Lister, but not other TC windows like Find Files or Synchronize Directories) called by Alt+Space (but not right mouse button) are dark (in a way as described above) again
I wish it would stay like that in final 9.50...
