I am very sorry I did not get to the page ealier, had some troubles.
About AION:

Then user has a small screen and runs an application with a lot of menus AION can not show itself. The last version uses less space than its ancestor (due to a location of a huge error :P).

The only moment when AION can make the menus stop functioning is because it got hanged. Though I have been trying to avoid such a situation (AION is checking every variable several times in different code places) I can't forsee every problem unfortunatelly. If everbody is having any problem please contact me:
