What happened?

When trying to set Win+Shift+S as a custom button shortcut, Windows intercepts the key combination before Mouser's shortcut capture dialog can register it, opening the Snipping Tool instead.

Expected behavior

The shortcut capture dialog intercepts the key combination before Windows processes it, allowing system-level shortcuts like Win+Shift+S to be assigned.

Steps to reproduce

1. Click a button to assign a custom shortcut
2. Press Win+Shift+S in the capture dialog
3. Windows Snipping Tool opens — shortcut is not recorded

Additional context

This affects any shortcut that Windows intercepts at the shell level. A workaround is to temporarily set DisabledHotkeys = S under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced in the registry and restart Explorer, which allows the shortcut to be captured. The value can be deleted afterward.

A proper fix would be to use a low-level keyboard hook in the capture dialog so Mouser receives the input before Windows does.

Hello, I had the same issue, i solved it like this: i manually typed into the custom shortcut "Super + Shift + S" (without the quotes, and it works, i am on version 3.6.0.) !
