[DMDX] RE: Re: No BMP's or JPG's get displayed Hi Andy, This error (where the display fails after a certain number of trials)  sometimes happens to us when we use NVidia cards which require the use of  the "-buffers " option on the command line. Try running DMDX with "-buffers 4" and see if this helps. fingers crossed, Matt At 12:03 10/11/2004 +0000, Andy wrote: >Hi Mike, > >IÂve just done a Âsystems restoreÂ to a few days ago, and IÂm back to my old >problem of only some graphics being displayed (older version of dmdx being >used).
