Search Input Field in Toolbar Doesn't Work

Okay, so after a few weeks of frustrating investigation, I still have no clear indication what is going wrong. I'm even getting the same toolbar search problem with one of the RH test projects published to the server! (I've also noticed that not only is the toolbar search a problem, but I'm not seeing the correct search options along with my search, like the "And" searching that I have enabled for the project.)

I did find a strange workaround, however, and I'm wondering if this will perhaps inspire any brilliant breakthroughs from the community...

On a whim, I decided to open a random topic in a new tab, isolating the .htm page itself. From that topic, if I click "Show" to reveal the navigation pane and toolbar again... voila! The search toolbar works, and the appropriate search options are present:

After using the "workaround," the URL of my project is different (Test Project vs. Please enter Project title here), and the title in the browser is also changed, as well:

• The end of the original (broken toolbar) URL: /robohelp/server?%26area%3Dgeneral%26mgr%3Dagm%26agt%3Dwsm%26wnd%3Dconditional_build_tags%7CTest%20Project%26tpc%3D%2Frobohelp%2Frobohelp%2Fserver%2Fgeneral%2Fprojects%2Fconditional_build_tags%2FGeneral_Office_Information%2FMission.htm%3FRINoLog28301%3DT%26ctxid%3D%26project%3Dconditional_build_tags
• The end of the workaround URL: /robohelp/robohelp/server/general/projects/conditional_build_tags/conditional_build_tags.htm#General_Office_Information/absence.htm
  • (Note that this URL indicates the topic.htm, even though I was on an entirely different topic at the time.)

Any idea what the heck is going on?

Is the “regular” search button working? Have you applied all the latest hacks for browser “security” fixes? There’s ones for Chrome & IE10/11.
