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?

There isn't enough room to display all the information. This is often caused by numerous words NOTAMs being shown on the map for the same area. Try turning off NOTAM display on the map.

Ok, thankyou. Turning off NOTAMs doesn't help. I think it's because there are many of the same radio frequencies listed against different levels of the TMA. I suppose the non scrolling text-box display is always going to be prone to having too much info. Could be time to implement a different display approach that can scroll. Low prio I guess.
