'Camera transpose mode' has been doing this to me for a long time on every aircraft, regardless if I have anything bound to it or not. Hovering over it tells me nothing (see pic). It also renders 'camera transpose' non functional. The only thing that fixes it for me is to go to 'DCS World>Config>Input>Aircrafts>Common>Mouse', and edit the 'default' .lua file. This is what it normally says under 'keyCommands' in there:
{combos = {{key = 'MOUSE_BTN2'}}, down = iCommand_ExplorationStart, name = _('Enable visual recon mode'), category = _('View Cockpit')},
{combos = {{key = 'MOUSE_BTN3'}}, down = iCommandViewTransposeModeOn, up = iCommandViewTransposeModeOff, name = _('Camera transpose mode (press and hold)'), category = _('View Cockpit')},
{down = iCommandCockpitClickModeOnOff,     name = _('Force cursor to show on/off'),    category = _('General')},
},
 
I notice it has mouse button 3 (middle click) listed for camera transpose, even though essentially every aircraft/crew position in the game uses a double middle click by default for 'Force cursor to show, toggle'. If I edit this lua by adding a third '{combos' like so:
 
{combos = {{key = 'MOUSE_BTN2'}}, down = iCommand_ExplorationStart, name = _('Enable visual recon mode'), category = _('View Cockpit')},
{combos = {{key = 'MOUSE_BTN4'}}, down = iCommandViewTransposeModeOn, up = iCommandViewTransposeModeOff, name = _('Camera transpose mode (press and hold)'), category = _('View Cockpit')},
{combos = {{key = 'MOUSE_BTN3'}}, down = iCommandCockpitClickModeOnOff, name = _('Force cursor to show on/off'), category = _('General')},
},
 
the red exclamation mark goes away and restores camera transpose functionality. Slightly annoying that I need to do this after every update or if I run a repair.
