What is going on here? Patchmanager has been playing up all day, getting progressively more and more messed up. At some point it listed as a patch a similarly named stand-alone application. Unti, in the end, it all toppled over like this: Attachment 40170 (Been spinning like that for the past 10 minutes.) EDIT: a reboot seems to have sorted it out, at least temporarily. I had a brief issue with a patch in the web catalogue appearing with an empty description but a Silica restart from Utilities has fixed that.
