In trying to figure out how to change the view of my form responses yesterday, I clicked on a filter which resulted in getting a completely blank page. There is no way to click on anything as there is nothing to see. Right clicking does not bring up any viable options. I can't sign out. I can't do anything. HELP!
If you find FormsCentral isn't responsive, refreshing the page may help, but you may lose some changes you made. I hope you've got out the situation.
However, what you encountered sounds like a bug. Can you please share the form with me at firstname.lastname@example.org and let me know how you run into the above situation?
