Yes it is popping up because of browser changes, never has been a https site. It is a public site so there is nothing to secure.

Regardless I have been able to make sure that the other software that goes along with TTOL software will not run in the "secure" mode. I have to make the changes on the server and then a bunch of modifications elsewhere so it will happen sometime in July.

The end result will be the same that you have now and the same information that is publicly available will still be publicly available, just you will not see the nag screen.
