I have installed the DIAdem evaluation software on my WinXP laptop. When I run the application, I can read in data and manipulate it; however, some of the buttons/functions do not work. specifically, the zoom features, and cursor types can not be changed either via the radio buttons, or drop down menu. I have installed the application on other WinXP machines and it works fine. Are there known compatability issues? If so, where can I find a resource? I do wich to purchase the software since it is exactly what I need; however, if I cannot use it on my field computer then I will be unable to buy it.
