@prsadhuk 

> These don't help on the system I have tested on. There's something else going on. The test is basically about verifying that clicking on a disabled menu item doesn't dismiss the menu. I don't think it does. If I comment out the press/release the same exception occurs. And visually you can see the menu disappear and then reappear. What it looks like is that the call at line 86/91 to mouseMove which returns the pointer to the "menu" location causes the list of menu items to disappear and then quickly reappear. Sampling if the menu is on screen at that time will cause the error. It only happens once .. very odd ..

Ran the updated test MacOS 14 ARM, thought the test passes there seems to be an issue similar to what Phil described earlier - the menu appears then disappears and appears again quickly for the second scenario - when the menu is clicked and glided through the dropdown. I have attached the screen recording to the JBS.
