I'm using the SGP latest version 126.96.36.199 with Ansvr 0.18 (the offline Astrometry.net solver). Sometimes (not every time), SGP will do steps 1 to 3 flawlessly but will then capture the validation frame for step 4 and just sit there, saying "Image preview opening...". After some minutes pass, it simply aborts, parks my mount and closes my roof.
If I close SGP and reopen it, then it tends to work. Keep in mind my CCD camera is working perfectly as once plate solving works, it captures exposure after exposure without a hitch. I think I need to ensure that there's no image open in SGP (such as the sequence's stored image or a recently captured exposure) to guarantee plate solving works. It's as if having an image open in SGP stops it from somehow downloading the plate solving frame.
Is this a reported bug or am I alone? Thank you!
EDIT: My PC's specifications can't be the issue as it has an Intel Core i5-4500U CPU, 16GB DDR3 RAM and a 250GB SSD. I'm running Windows 10 Pro.
