I'm using RM 3.0.145 and stepping through the rigs in "My Profiler", double-clicking to load and preview. All well and good.
However, if you rate your current selection, then double-click on another rig, the rating vanishes.
I think the same thing was happening to favourites, but in that case I was marking them in RM and stepping using the browse button on the Stage.
This will now be the 3rd time I start again to preview all the installed rigs... <sigh>
