The ampersand character being the default menu access character is not being properly escaped in some areas of the app. Whenever an ampersand is used in a Label field or in a Page Label, it is converted into an underscore (_) elsewhere as if it's being interpreted as a menu access character. For example, if I enter "This & That" in the Label field, it shows as "This _ That" in the autocomplete list. Likewise, if a Page Label contains an ampersand, that ampersand is converted to an underscore in any flags made from that page. It's a minor nuisance but may be occurring in many more areas than I've found.
