Tools > Options > Scripting has a new Language Dropdown.
It should be a DropDownList instead of a dropdown, otherwise, any character the user types causes a popup alert and the user can be left with a garbage value.
Further, there probably shouldn't be an explicit warning that a restart is required, as a great many options on the Options dialog require restart and showing this warning for only one of them may be misleading.
The control will be fixed. We will probably add some kind of notification to all the settings that require restart.
