I thought this was an issue only in the scheduler, but tonight I discovered it's not.
Every time my guider exceeded its guiding deviation limit a window would appear asking me to confirm my camera. I only have one imaging camera (ASI1600MM) and one guide camera (Lodestar X2). In the past, this box had a timer and would close after a few seconds. Now it does not, It just stays on screen, and flickers. Yesterday when this happened, it would not allow the scheduler to resume.
