It asks whether or not I want to resubmit which I never had to do before. DAMN!
I get that from time to time, especially after using the search function. If you reload the page by highlighting the URL and hitting enter it clears. I work from a iPad FWIW, so the behavior may vary.
Yes - that is qmap form handling when you’ve done a search; it still retains search entry. Your solution is the correct one, clear the search, then go back to URL and enter clean.
