I have just loaded the new 4.0.0 versions into the rotator and the shutter, however there is a bug that causes the manual rotation control (ie the rocker switch) to stop working after a period of time. I suspect this coincides with when the new hold feature stops holding. The dome can still be rotated with an ASCOM command, and in fact once the dome is rotated a tiny amount, the manual control starts working again. In regards to the new hold feature, it makes an irritating sound, and I've never noticed a problem with the dome rotating when it shouldn't either. Can we have a feature to disable this please.
