I keep having the same problem too. It's so frustrating! Every time I switch books, Chrome crashes on me. Some books aren't set up for web connectivity. Some are. Doesn't seem to make a difference. I have to run payroll through a few different companies so I have to keep the connectivity active. I hate that I had to upgrade in the first place. I miss being able to have two books open at the same time. Bring that function back!
