I'd tell you what the beta release is (4.5a, beta 2?) but it just opens and hangs, reminds me of the original logos 4 for windows a couple of years ago. Worked fine until this update.
No indexing happening, but I can't open or close anything I have to force close it. Hoping for an update soon. It has all the memory or cpu occupied I'd say.
