With all my time at the hospital with my wife, apparently I never got B9. But, I just found an update to L4 without a version number. I'm going to assume (terrible thing to do) that this might be RC1 -- but there's notihing to confirm this for me -- the Help About screen is silent on the issue
Just after running the update, I opened L4 -- checked to see what version, noticed that I'm still trying to get this 1.6 gb update downloaded, I got a crash notice (can't tell if it's the same one I reported last night as I'm now running a different version of the application)
