Bug: Unable to close warning dialog with Hammer's Keybinds selector

[dot-64]

Describe the bug

When changing a keybind in Hammer's 'keybinds' selector menu, it causes this error when that keybind is already assigned to another action. This makes the dialog pop up with #Message_Box_Ok and I am unable to close it.

To Reproduce

1. Open Hammer's tools menus and choose the 'Keybinds' button from the drop down window
2. Change a keybind in the editor to one that is already being used by another action in Hammer.
3. Try clicking on the Message_Box_Ok dialog to close the window.

Expected Behavior
