I uninstalled Sigil manually, cleaned the registry of every entry that related to Sigil - there weren't that many, some MRU entries and those Toasts I posted yesterday and a few other insignificant entries. Then I reinstalled. Which IMO is better than renaming.
What did surprise me is that trolltech writes entries for every QT application I have on my machine - including several calibre portables
