Doesn't take two nibs. Just one that's loaded two times. This is
probably not the most elegant technique, but it works....

+ (void)displayModalForWindow:(NSWindow*)inWindow
{
   static MyController* sPanel = NULL;
   static MyController* sSheet = NULL;
   
   if(inWindow)
   {
       if(!sSheet) sSheet = [[MyController alloc]
initWithWindowNibName:@"MyNibFile"];
       [NSApp beginSheet:[sSheet window] modalForWindow:inWindow
            modalDelegate:sSheet
            didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
            contextInfo:NULL];
   }
   else
   {
       if(!sPanel) sPanel = [[MyController alloc]
initWithWindowNibName:@"MyNibFile"];
       [sPanel showWindow:self];
   }
}

This is heavily trimmed but I don't think I broke it in the process.
