It is good to know that the ASCOM camera simulator is not designed for Solve and Sync. Perhaps you might consider deactivating those two keys if a user has selected such a camera although I am not able to understand why it should be that way.
A better thing would be to “allow” it. After all what is simulation for? In my case it would be very helpful to know what works and how in order for me to plan. It would help to see if sync actually happens and, in simulation, I can slew my scope to a particular target.
In addition, I strongly suggest placing an obvious button for the Blind Solve and for solve using a solver right inside the user plate solving tab interface. At the moment, a right click on the opened image is the only way to find the feature and that appears to be an undocumented feature only a lucky few may be aware of.
In any case, thanks for freeing me from perpetual search for how to solve and sync using a simulator.
