   code won't run on test computer
  Hi all,I have a little programm we are working on a fairly simple 2d game and we have an old computer to test it to see if we get an acceptable framerate on those machines. the problem is the tests run perfectly on my own development maschine(athlonXP1800/GForce3) but on the test computer p1mmx with S3 trio64V2 it quites when directx is initialised with this code: LPDIRECTDRAW7 LPDD_Create(HWND hWnd,DWORD dwCoopLevel){//declare object pointerLPDIRECTDRAW7 lpdd;//create objectDirectDrawCreateEx(NULL,(void**) &lpdd,IID_IDirectDraw7,NULL);//set cooperative levellpdd->SetCooperativeLevel(hWnd,dwCoopLevel);//return pointer to objectreturn(lpdd);}is the S3 trio chipset not able to work together with directx? or should i look for something else.thanx, 
  Are you sure DirectX 7 or better is installed on your test computer? And you might want to start checking return values for error codes. ;  on the test computer is installed:win98SE with directx9.on my development maschine:WinXP with directX9
