same issue here (on mac, snow leopard) … will update to xcode 3.2 today and try again.
Also, when scanning for updated plugins I get a few issues …
1 - scanner scans the default directorys even if they have been removed from the list
2 - some plugins show up every time … disappear if I do “remove plugins who’s files are gone” … but then reappear on subsequent scans. How can that be happening? The files aren’t even there … this is using the VST host compiled version … so I know it resaves the knownpluginlist each time … but it doesn’t seem to be forgetting plugins it has seen that are now gone.
Anyway, best luck with the work Jules … will download the tip monday.
