When you make a search, e.g. on admin_users.php, if you backspace the search out, or clear it (ctrl a and delete/bkspc) it keeps the line that says "Search results for" even though the search has been cleared and the table reset.
I noted this on the list. I'll take a look.
FYI - this does the job in Firefox, IE, etc but not Chrome....
I might be leaving Chrome soon anyways...it's starting to be poorer on the usability scale and a lot of our applications at work aren't tested on Chrome (for whatever reason)...
Our stores use Chrome and we don't have an issue so maybe there's something more than just the code I gave you. I'll check and see if I can find anything.
