Menu shortcuts dont work in Windows while menu.popup visible

In my app, people can select an area.
When they do that, I popup a menu that contains clones of Edit/Copy Edit/Cut and these have std keyboard shortcuts of CTRL-C and CTRL-X
On windows, while this popup menu isivisible, those shortcuts dont work.
It just goes ‘ding’
If I dismiss the popup, they work fine.

Is there a reason/ workaround?

If the menu is up and you press the access key (the letter denoted by the ampersand when editing the menu items, which is underlined in the menu display) for the item you wish to use, does it work? I believe this is expected behavior on Windows.

The menus don’t have an underlined letter. They show CTRL-X and CTRL-C next to the text, as I would expect.
I should add that the shortcuts work fine when the menu is visible on a Mac.
But it almost ‘feels’ as if the popup menu is a [new window that lacks a menu] rather than a ‘real’ menu

Did you assign them the access keys I was talking about before by adding the ampersand (&) before a character in their Text, as is done for the MenuItems you’re cloning?

If this is done, then pressing “C” while the menu is visible should perform the Copy operation.

Bigger picture: what I display was a menu item, with one child that is a submenu with kids.
On Mac, all keyboard shortcuts work fine.
On Windows, the keyboard shortcuts (which work fine on the window normally) , don’t work at all.
If I popup the contents of the the submenu instead of the parent, things do work.

I really didn’t want to do it that way, but like so many many things, I’ll guess I’ll just have to lump it.

Anthony’s question is a good one, still.
The ampersand way is known in the Windows world. Making your menu item’s text to “&Copy” will show as “Copy” with C being underlined. Then, the C key would trigger that item (obviously, avoid having several items with the same character).
That’s different than on Mac; I’m not even sure Ctrl+ works in a contextual menu on Windows at all (as you said, it’s considered as another window there).
(some of what I wrote are possibly strong assumptions).

Underline shortcuts I understand.
How they work in some other language confuses me , however
But the keyboard shortcut for copy is CTRL-C and the keyboard shortcut for Cut is CTRL-X
Whether or not there is an underlined C , and there is certainly no X to underline

They don’t work on Windows while a multi-level popup is visible.
The equivalent CMD-X and CMD-C do work on the Mac.

I understand ‘I wouldnt do it that way’ responses, but what I’m saying is ‘the shortcut that works in Word , is what people will expect my app to do’
