I have this old 32 bit computer that I keep around to run old magnificent printers. Hmm... but it runs great, and i think it is a lot better than 64 bit, even in Windows.
So I just installed Ubuntu 12.04 on it (which is actually the best OS for old machines it seems), and then I put in BA just now. It runs nice. I have not put in any modules, but I ran the dual window, and it seems to work just fine. If I change a verse,though, then I have to click the dual window icon, and click sync.... but maybe, that is the design of it.
So I got to thinking... maybe, the dual window problem I have in my other computer is the 64 bit format. Hmm... but I was told we have to go to 64 bit, and I think I believe this. Well... I think I'll try it on another 32 bit computer soon.
