Multiplayer Menu CTD

[AMVI_Superblu]

I am experiencing a strange issue..
while flying on singleplayer mode everything works fine..
but when i am flying multiplayer i can fly, fight, etc. then after RTB if i press "ESC" key to get i.e. a new aircraft my sim crashes to desktop.
Anyone experiencing the same problem ?
Devs know 'bout this ?
Anyone found a way to fix this ?
Thanks
