- what OS (Windows Xp/Vista, Mac etc.) are you running ?
- what graphics card do you have ?
- does the problem occur with any aircraft, at any airport ?
- is there any output printed to the console (black window) ?
I suggest to redo a fresh installation of flightgear 2.4.0, but before try to delete the /.flightgear.org folder ( if you have a linux OS ) or "C:\Documents and Settings\your name\Application Data\flightgear.org" if you have a windows OS
it could be also a driver issue ( bugs in your driver about shaders 2.0 ), try another version for the graphic driver
