Sorry Jerry, I thought you had written, in that thread, that you hadn't yet used the ASCOM beta release for telescope control. I know you had written that, at that time, you hadn't had any problems with the beta release but I thought you had said you didn't put telescope control through its paces. I know that other users, farther down in the thread in the PMC-8 group did indeed have problems with the beta version of ASCOM (using the EXOS2 mount, I believe)... then reverted back to 6.4 and all was well again. This was including telescope control. I, personally, never tried the beta version but I know others were reporting frustrating problems and then reverting back to version 6.4.
Hi Patrick, no worries. I tested the release on my laptop with an iEXOS 100 mount, and then after I was satisfied that it didn't break anything, I upgraded our observatory platform and it seems to work fine. I actually did this before the most recent firmware update to the PMC-Eight. Everything still seems to be working okay, at least I haven't had any reports of weird stuff from the other astronomers. Problems could be system related in terms of Windows updates and such, or hardware configurations, who knows.
