Update:
Very strang. It appears this is only happening in chrome normal browser. Incognito and other browsers appear to be all ok, so I’m assuming it’s only my specific chrome browser that’s the issue and not the plug-in it’self.
Would be interested to know if anyone else has had this happen to them before though as I’ve turned off all extensions and it doesn’t seem to matter, yet chrome incognito works fine. Weird.
