Hello, I am just beginning to play around with the "effect" function and it is working fine, however after about 20 or 30 minutes of playing with it my computer crashes! This has happened twice. I get the Blue Screen of Death error and it only shows for a couple seconds (not long enough to read any details) although later I did get a prompt from Windows showing me where to find a dmp file and sysdata.xml file. So, I'm not sure what's happening, but I wonder if its related to not enough memory or something. Is there a memory leak occurring? I just started out with the example "effect" code and then started tweaking it with different vectors and colors, etc. I'm not sure what would cause the crashing. Anyway, let me know if you have any thoughts. Thanks...
