With Popup Pro, my popup form is showing on every webpage a visitor visits, no matter if they competed the sign up form, clicked out of the popup window, or clicked the x to dismiss the popup. It continues to appear with every click through the site. It seems like the cookies may not be working or something. I've double checked and I do have cookies enabled and no browser add-ons at all, so that's not likely to be the issue.
I've had several reports of this from angry customers outside of my own testing, and I've personally been able to see the behavior on a Mac in Chrome and Safari, as well as on a completely separate desktop PC in Chrome and Firefox.
The popup form where this is happening is the 'Front Page: Not Logged In' form. It is currently inactive because I've had so many complaints. I enabled support access in the dashboard, so please feel free to activate it for your own testing; please just deactivate when finished until I can verify this isn't happening anymore.
