When we are using the SBIG w/AO driver, we are finding that the mount position fails to update regularly in MaxIm. We're running a STT with AO-8 and an Astrophysics 1100 mount. The symptoms are that after a slew or cursor-key adjustment the 'bullseye' on the sky map stays on the previous position and the cursor-keys remain greyed out. There's also a delay in the dome following (it's getting the old positions) that can lead to weird dome oscillations. We can (usually) force the position to update by right-clicking with the mouse on the latest image displayed in the main MaxIm window. We don't get this behaviour if we drive the same camera with the SBIG Universal driver (but then we lose the guiding / AO). Has anyone else seen this? Any suggestions?
