Hi. First off I''d like to say that "Using Direct3D For 2D Tile Rendering" is a great article, not just for tile rendering as I learned a bit about Direct3D as well. I''d like to see a lot more articles of this caliber. I do, however, have a problem with it. The examples run perfectly fine the first time I run them but when I try to run them a second time (excluding after reboots) it peforms some kind of error (can''t remember right now). I remember the author commenting on if you don''t release Direct3d, then you possibly can''t run another direct3d program. I checked the source code just to make sure it *was* included and it was. I''d really like some help because I view this as the perfect time for me to start Direct3d programming and I don''t want it to end so quick. Thanks, - Ace
