I have been using Visual Fortran 6.0 and have updated it to 6.1a. Array Visualizer worked fine in its original setup (1.0), but since updating VF to version 6.1 (and the to 6.1a), AF works only in 256 color mode. It seems to be some incompatibility with Voodoo5 5500 display card. Has anybody else observed this and is there any cure? I have tried with all the latest drivers for Voodoo 5. <BR /> <BR />Markku Kangas <BR />Finnish Meteorological Institute Tue, 28 Aug 2001 18:56:59 GMT https://community.intel.com/t5/Software-Archive/Array-Visualizer-and-Voodoo-5/m-p/964651#M22562 mtkangas 2001-08-28T18:56:59Z https://community.intel.com/t5/Software-Archive/Array-Visualizer-and-Voodoo-5/m-p/964652#M22563 Array Visualizer uses OpenGL, and the OpenGL hardware support of many consumer video cards is rather poor.
