I'm very reluctant to assume responsibility for bugs in others' software... so this is for information only. I started the ASCOM Profile Explorer and Under Telescope Drivers > ASCOM.SoftwareBisque.Telescope I see those settings listed. This means that they used the Profile object that is supplied to driver authors as part of the ASCOM Platform Developer's kit. I happen to know that the Profile tool saves its data in the Windows Registry under HKLM\SOFTWARE\Wow6432Node\ASCOM\Telescope Drivers\ASCOM.SoftwareBisque.Telescope. What I don't know is if/when the driver will (re)read that info if you change it in its saved settings.
