Thanks. Did that, ran into java.lang.ExceptionInInitializerError, but after another update a few hours later, it's now working.
btw--I ran the release version yesterday, saw few leafs there too for the several hours. After 8 hours, 28 leafs were active, but it took quite a while.
Also, I switched skins to the default for the purposes of a screenshot, but when I switched back to the OS X Pinstripes, the search tabs remained in the Windows mode. I couldn't get them to back to the Pinstripe tabs before I had to shut down.
