问题
I have a Winform with a menu strip that hosts a WPF control that has some buttons. The toolStripMenuItems and the WPF buttons all have access keys set up.
When I hit "Alt", the letters for all the access keys become underlined as expected. When I hit the "Alt" key a second time the lines disappear on the toolstripMenuItems but not on the WPF buttons. The access keys still work.
It appears that the UI is not keeping up with the keystrokes. Is this by design? And how do I get uniform behavior across all controls in my app?
