Up until the last couple of days, I could type COR.Net in my Chrome Browser's address line and all is well.

NOW, in Chrome and Edge - I have to type www.Cor.net

IE seems to add the www automatically...

The site recently (five months) had a MAJOR overhaul.. I am wondering if this is a new thing they've done or if it's on my end.

I would hate to see them lose traffic.
