Yes, last week. Will try it again today, and reply if it fails once more to do as it's told! If it doesn't take care of it though, I will switch to the uninstall, and only install it when I want to use it, method.
Bwa ha ha ha!!! Reinstalled from the Spotify.com page, changed setting to "Do Not Launch on Startup." First reboot -- Spotify starts. And, it posts a little message on the top left of the page -- Do you want Spotify to launch on startup -- yes...no. Worth a try, but...next reboot, howdy auto-launched Spotify!
