Very good. I think I misunderstood how it worked, despite it doing what it was supposed to in my program. > By the way, I have fixed a bug in the alpha blending of PaintImage in revision > #3926. Tell me if you notice the change. I'm going to try recompiling again since revision 3910 involved SDL, but right now I get the error "The program has returned the value: 127" as soon as Client.Initialize() calls Render.Initialize(). The procedure call raises the error immediately, not a line inside the Render.Initialize() procedure, which is interesting. I'll let you know the results when I compile again to 3910 or higher, and if there's any different in appearance or frame rate since the PaintImage bug fix. -- Kevin Fishburne Eight Virtues www: http://sales.eightvirtues.com e-mail: sa...@eightvirtues.com phone: (770) 853-6271 ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
