Thank you for your response!

If I try to copy/paste the URL of this very page into a Google Chrome browser, the page fails to load, and I get the "Bad Request" notice. If paste it into a Mozilla Firefox browser, I have no issues. So I have been doing everything ProConnect Tax related in Mozilla, which I have no issues with. I just thought it was weird and figured other people would have run into this issue since a lot of people use Google Chrome as their main browser...
