PC Version 3.6.6.  If I move the mouse pointer to the south-east of LFAI near Paris, a white popup appears giving me airspace details and notam. That's great. If I do the same to the south-east of LFPL I cannot get the box to appear. In fact I cannot get it for anywhere over the central Paris region. There's definitely airspace there because it's under the class A airspace of Paris . Is this a bug or is there a reason why the popup doesn't appear?
