I didn't realize that the separate windows were associated with macros in different modules. So am I right in thinking that (a) the VBA editor will never display two different windows that contain different macros from the same module? but (b) if the user decides to edit macro A in module_1 and, later in the same session, to edit macro B in module_2, the vba editor windows for module_1 and module_2 will both remain open unless the user explicitly closes one of these windows?
