I finally made more time to play with Remote Desktop, to try to figure this out. After several more hours of experimenting, I am concluding that the problem may not be Remote Desktop, but instead some other limitation of my system or its interaction with Pandora/Saver2.
I have now successfully run Saver 2 from Remote Desktop -- which is great, since I can give "thumbs down" and "tired of this song" without having to run to the room where my server is located. However, sometimes a single track fails to save (even though it is a new one), for reasons I do not yet know. (I have reviewed all my Saver 2 settings, and don't see reasons why non-duplicate tracks shouldn't save.) Then, after a while, tracks stop saving altogether. If I close Saver 2 and re-open, it starts saving again. All the while, this is in Remote Desktop.
Now I need to see if this ever happens WITHOUT Remote Desktop.
Anyone else successfully using Remote Desktop? Any glitches?
Thanks.
