Thanks! I checked resource file, there is no multi language used. "LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US" is found in rc file.

That's true. The problem is in the whole resource file there is no "Shift+Delete" string found. "Ctrl+X" is used for "cut" button. Why does it show "Shift+Delete" when mouse hovering over it on some PCs? Thanks!

The default toolbar buttons means when creating this MFC application using application wizard, there is default toolbar generated; we customized other toolbar buttons but leaving "cut, copy, paste" untouched. Thanks

As I said in the post the "cut, copy, paste" toolbar buttons are default ones, the tooltip for "Cut" is "Cut the selection and put it on the Clipboard\nCut" was not added by our application. Don't understand why this "Cut" button's tooltip displays differently on different PCs, some PCs show "Ctrl+X", some show "Shift+Delete" which is kind of misleading.

we developed a c++ application which its GUI uses default toolbar buttons (cut, copy, paste). It's strange same executable running on some PCs when user uses mouse hovering on the cut button, the tooltip displays as Cut (Ctrl+X); on some other PCs the tooltip displays as Cut (Shift+Delete). Does anyone know the reason and how to fix it? Since Shift+Delete doesn't do real cut. Thanks
