I've been making small patches/improvements over the past couple of week. I just tested it on my computer and it worked just fine, but it does take a few seconds to complete if your database is large.
Since I've pushed out a couple of small patches silently, can you manually uninstall, get a fresh download of 1.6.7.2, and tell me if the problem remains when you try it on your computer. I can also give you a beta version of 1.6.7.3 if you want to try it out. It has improvements to how the clock time is displayed on the Public Display and improvements to how the Results Kiosk loads and scrolls through the results.
If you find it's still an issue then let me know and I'll log into your computer and watch it myself, but I've done it about 10 times today and it worked each time.
