I have on my computer a Mustek 600 III EP scanner and a Relisys Dimera 3500 digital camera, which both use TWAIN drivers. I cannot get both of them to work at the same time. When I have the camera working the scanner stops and vice-versa. Also I cannot get the scanner to work with Photo Studio 2.0 SE the software starts but as soon as the scan begins, the scanner stops and the program freezes. I believe the problem to be a conflict with the TWAIN drivers and would appreciate any assistance to resolve it
