  Hello again Robin,  I don't think I mentioned that the model of computer I have is a laptop, if that makes any difference, which I'm guessing it does, I think that's it for now. I sure hope you can help, or someone.   Hi Chris, Chances are, you don't have a graphics card for your laptop, and your graphics are coming off a chip on your motherboard. With that in mind, you won't be able to handle any game's that require a lot off graphics. Some of the more dear models of laptop's, do carry a graphics card, where the bottom end don't, and the bottom end laptop's are not upgradeable on their graphics.
I have a Latitude D610 and am running Windows XP Professional. I have copied all the system info. and it is as follows...        9/24/11                                  BIOS:  Phoenix ROM BIOS PLUS version 1.10 A06                        Processor:   Intel Pentium 1.86 GHz                           Memory:  504 MB RAM              DirectX version:  DirectX 9.0c (4.09.0000.0904)                        Chip type:  Mobile Intel 915GM/GMS,910GML Express Chipset   Approx. total memory:  128.0MB Current display mode: 1024 x 768 (32 bit) (60Hz)                          Monitor:  Plug and Play I hope that's enough information for any one who might be able to help me. My trouble is with a program I'm running called FlightGear. It's  flight simulation freeware and, I might add, it's pretty darn good, but I'm having a problem with an OpenGL error. The base program comes preloaded, I'll say, with scenery and aircraft and a person has the ability to download both from the FlightGear web site, which I have not done. All I have is what I downloaded from the web. I have a disc as well and have run into the same problem. Out of the 14 aircraft offered only 2 will work. With the other12 I get this....."Warning: detected OpenGL  error  ' invalid value'   at after  RenderBin : : draw( . . )     That's it verbatim. I've gone to the FlightGear web page and according to an answer forum, it's unanswerable, unless I just read it wrong. My guess is that the chipset just can't handle it. Can I do something with this particular computer to remedy the problem or will I have to upgrade to a better computer? I just don't understand why this is happening, I can use a Dehavillin float plane and a Seneca 200t twin engine but not a dang glider or WWII biplane which, to me anyway, is a lot less complicated. But I far from an expert when it comes to computing. I'd have to say I'm at the beginning of the novice stage. There is just so much to understand and I'm really not the sharpest knife in the drawer, but in the same breath I'm not the dullest by far. I would sue appreciate any help I could get, in the mean time I'll fly with what I have and be happy and maybe learn a thing of two about to navigation and the use of the instruments that help with that sort of thing. Thanks.  Chris
