    I am converting an application to cocoa. I have a menu that has 25 items. Only one selection is valid at a time. I am having trouble with removing the checkmark from the current item (set in IB) and setting a new checkmark after user selection of that item.
    I have a single IBOutlet for all the menu items. Based on the tag number, the program does its thing. So I know the item that was checked, as I have saved its tag. And I know the new item selected as it is sender. How can I recover the NSMenuItem for from the tag. this is what I tried, which does not work.
    Any help would be appreciated.

    - (IBAction)doSelectionMenu: (id)sender
    {
    int currentTag;
    NSMenuItem *theMenuItem;

    currentTag = active + 400;
    theMenuItem = [NSMenuItem itemWithTag:currentTag];
    [theMenuItem setState:NSOffState];

    [sender setState:NSOnState];

    }
