User Interface hanging when disconnecting SkyX driver

Sequence Generator SGPro Support

Description

Most of the time when I try to disconnect from the SkyX ASCOM telescope driver, it hangs the user interface in SGP. I can’t move any windows or click on anything, although if I hover over the “X” in the upper right of an SGPro window, the “X” turns red. Clicking on it doesn’t do anything though. It’s almost like there’s a hidden dialog box, but I can’t see it and can’t move the SGPro windows.
SGPro is using a few percent of the CPU during the hang. I have to kill SGPro via the task manager. When I did it today, the mount was parked via SkyX.

Last two lines in the log file prior to killing SGPro are:
[12/07/20 08:10:10.654][DEBUG][Main Thread][NONE] Disconnecting ASCOM Telescope: ASCOM.SoftwareBisque.Telescope
[12/07/20 08:10:14.176][DEBUG][Equipment Connectivity Thread][NONE] SGPro thinks the telescope is connected, but it’s not, syncing UI…

Useful Info

OS: Windows 10, fall 2020 edition
Ver: 3.2.0.613

After I killed SGPro using the Task Manager, the following entries were added to the log file:

Not sure what is going on here at a glance… We haven’t seen any other SkyX users report this issue so might be something specific to your rig. I’ll see if I can take a look.

Ken,
have you been able to look at this?
Is there any additional debugging I can do to help determine where the problem is?
Thanks - Eric
