An NSMenuItem's view (instance of an NSView subclass) isn't highlighting on hover

Maybe you should try it this way:

#define menuItem ([self enclosingMenuItem])

- (void) drawRect: (NSRect) rect {
    BOOL isHighlighted = [menuItem isHighlighted];
    if (isHighlighted) {
        [[NSColor selectedMenuItemColor] set];
        [NSBezierPath fillRect:rect];
    } else {
        [super drawRect: rect];
    }
}

I'm not sure if I understood your question. I think you mean the following: The Menu opened and all your drawings stopped drawing. I think this is because the opened NSMenu stopps the UI' NSRunLoop its thread. One of both. You should try to do your drawing thread-safe in an other thread.
