Whenever I go to 2d panel mode in DGIV, and press ctrl + downarrow to switch to bottom panel mode, my game gets incredibly buggy and starts lagging unless I switch back to the top panel, which has les options.
There might be a shortcut assigned to ctrl+down. Have you tried that key combination outside of Orbiter? Does it do anything (say, flip the display upside-down?)
What exactly happens to Orbiter when ctrl+down is pressed? Graphical glitches, freezing? Does it happen for other 2D panels (Ravenstar, Shuttle-A, NASSP?) Does it do anything when a 2D panel is not available? Do Ctrl+Up Left or Right do anything funny too?
Multivac would tell you 'there is as yet insufficient data for a meaningful answer.' :tiphat:
When I switch to the bottom panel, my game starts lagging, and also my cursor does, so i have to switch back to top panel to fix it. It happens on XR2 Ravenstart too, and no, CTRL + Downarrow doesn't do anything outside th orbiter, It is not a shortcut to any appliaction.
