I'm running Maxim DL6 Pro under Win7 on a Dell desktop. This is a new machine and new installation for us. I've downloaded and installed the latest ASCOM drivers (platform 6.1SP1 and SmartFocus Focuser 4.0.1). We have a JMI NGFxT CM focuser that I can't get Maxim to connect to. In Maxim > Observatory Control > Telescope > Setup, I choose focuser = JMI. But when I try to connect to the focuser, Maxim crashes with a popup error message saying Maxim quit unexpectedly (I noticed!). I can connect to the focuser using JMI's focuser software and control the focuser just fine. I can also connect fine to our telescope (Meade LX200 GPS 12") and control it using Maxim DL. Thanks in advance for any tips!
