I'm using a third party library that has some fast alpha blending and special effects for 2D blitting. It comes with several drivers (.dll's)and there is a call that you place in your code telling it where the drivers are located. During development, I just had them sitting in the top folder of my project along with my code files and everything worked fine. I find however that if I remove them and try to put them back in the same spot, or I recover the whole directory from a backup I get errors stating that the drivers cant be found, despite the fact that they are in the same place. Admittedly I'm not totally familiar with how drivers operate. Is this typical? Any suggestions or even general info on the theory of drivers would be appreciated. Thanks Duncan We have assumed control... Edited by - The Lemurs on January 24, 2001 2:45:17 PM
