PS++ is removed from the list of installed plugins on upgrade / installation of MP 1.5. But you see it as a compatible plugin in the list of known plugins in the 1.5 pre-relaese, since this is seen as a 1.4.x version. You won't see anything of PS++ any longer when you install MP 1.5 final.Just a suggestion, this should be mentioned in the upgrade instructions when 1.5 hits the shelves. Something like "If you have PS++ installed, uninstall it before doing an upgrade to MP 1.5" (maybe even in big letters) otherwise I predict a lot of bug reports. Or is this problem going to be handled a different way?
