I was using RM8 earlier today. After closing it and later restarting it, all I see is a white screen with RootsMagic 8 and my database path in the top header.
I am able to X out to close it.
Task Manager shows .0 to .1% CPU and 108.2 MB memory.
When I worked for major companies “Turn it off and turn it on again” was always the first piece of advice given by IT Helpdesks. (Apart from RTFM but we won’t go there!)
