Definitely strange. Not sure what would have changed in the latest Joomla, but either way, I'm glad we could help narrow it down... and that it wasn't our fault in the first place.. we hate bugs
As always though, should you need anything else, just let us know.
Finally, if you haven't already, please consider leaving a rating and review for SCLogin, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
