I upgraded Chrome and Opera, and tried on Edge and Firefox as well. All 4 have the same results when navigating to this URL:
https://www.visualcron.c...;search=test&forum=3 The work around for me is to NOT use the Search bar at the bottom of the forum page, but instead click on the Search link at the top of the forum page and then search from there.
Clicking the Search link at the top takes me to here:
https://www.visualcron.com/forum.aspx?g=Search At that point I can see the Loading... pop up function as expected, where it pops up and then after getting the results it goes away and I can scroll through the results.
