What the heck?! Is anyone else getting ERROR REPORT bX-hg9hg2 ???

I've been seeing this (see below) ERROR REPORT for months(?) now, but sometimes it's not here or it goes away on it's own as quickly as it came.  I use IE (Internet Explorer) which I prefer, mostly because that's what I'm used to.  Anyway, this pop-up is very annoying and has actually prevented me from posting the past two days or reading other's blogs. 

I'm only here now because I persistently kept refreshing the page and clicking on anything I thought might help. Still baffled.  I really don't want to use Chrome, but should I for Blogger? Suggestions, please?
