I just tried my Windows 8.1 laptop with all the latest builds:
SGP 2644 beta
SBIG API 1.3
New TheSkyControlled Telescope Driver
Windows 8.1 64 bit fully updated plus I uninstalled the older PhD/API/SGP/TheSkyControlled Telescope Driver softwares and ran a registry cleaner before installing the above new versions.
I had instant crashes of PhD trying to do any kind of exposure with PhD2, even darks (in fact, I could not get beyond guider darks).
It was fine when I connected direct to the camera selecting SBIG instead of the SGP API.
I will post this to both PhD and SGP forum because it looks to be either the API,PhD, or some combo.
Original logs are at:
FYI, I had forgotten to enable API logging but have now done so and here are the new logs, very short as it crashed when I asked PhD to take a set of darks, these also have the latest SBIG drivers so everything used is current:
Given that I was also having crashes when trying to track (darks were fine) with the older 2.3.x and older API and older PhD (these are on my desktop), I am a bit concerned that I may have an iffy setup in terms of getting image data. That is a real puzzle since those versions worked for months with the same hardware and same connections. I will try the 2.3.x and a shorter guide time tonite (as timeouts were the problem with that).
UPDATE: Last night I ran the entire night with 188.8.131.521, PhD 2.3.1.i, and API 1.1.0. This has been my normal go to set of versions for some time. Although I have seen a few PhD crashes at times with these, overall they have been very good and last night ran all night with 3 different objects as well as a flip and darks with zero trouble. I would like to test the beta and will do so on my laptop once the API issue is fixed, my desktop production machine will have to stay 2.3 et al until 2.4 and the API are stable.
WHAT I CAN SAY FOR SURE is that the 2.4 beta crash with the API is consistent and immediate - it will basically not allow PhD to work at all with the API.
That needs to be dealt with before anyone with an SBIG self guide camera can even test the beta.
