On 2 consecutive flights I experienced being "stuck" in the bombsight view (v) after alt tabbing to view another window. By stuck I mean I couldn´t change back to cockpit view, but I was also unable to control the plane, the viewing from the bombsight, enter then chat or open the bombbaydoors, in fact I couldnt even finish the flight with Esc or quit the game. Even after closing all other windows I could not do anything. The plane flew on in the current heading. Potentially an important bug since many players use alt tab to check their flight plan during bombing runs.
