DNN7.3.# using Website Creatives' Generic3 framework.

When I click on a link that has a modal warning "speedbump" (Warning, you are leaving the site, continue or cancel?), the modal is not appearing. If I load the page in an Incognito or Private browser (that is, this behavior is true in both Chrome and Firefox), then the modal will appear and allow the user to click Continue or Cancel to go to the link. Since it's working in Incognito, I wonder if there is something getting cached somewhere, but clearing all data/cache/hard refresh...does nothing. Without the modal appearing, the link does not work, so if this behavior is happening on the client's end as well, then the site has not links working to go to related but different domain sites (Facebook, local areas of interest, emails to staff members, etc).

I noticed a few questions for modal issues that suggested checking JS and JQ in the console, but console only shows my jQuery.browser is deprecated, and the function does not reference classes or variables that could be involved.

Logging in as super-user on a private window - modal stopped working. I logged out - modal works. So there must be a conflict but now how to find it!?!?
