I have the beta installed on my 64 bit laptop with Ubuntu 13.04. (I had to give up on Mint, as it was so slow and klunky, and got more so with each update. Ubuntu is fast, sleek, and smooth, and now in 13.04, it is unbelievable how fast and nice it functions).
I opened the help menu first in my old BA version to verify its version number, and there was no way to make the About Bible Analyzer screen go away. I had to close the program from the launcher panel. After I upgraded, I had the same problem. There is no way to close the screen. I have verified the new version is installed, but in the launcher panel, the roll over still shows 4.6 -- but does that really matter?
I'm rather busy of late, but I do want to test out this new version, and I should make some more posts on it later.
