Mail 1.3.1 under OSX 10.4.3?

Question

After six weeks of trying to live with it, I'm still finding Mail 2.0.5's user interface considerably less configurable and more annoying than Mail 1.3.1. I'd like to go back to Mail 1.3.1, which I found in my "Previous System Folder".
However, double-clicking Mail 1.3.1 produces no result. The application doesn't launch. Showing package contents, navigating to
Mail --> Package Contents --> Contents --> MacOS --> Mail and double-clicking Mail brings up a Terminal window that gives me the following:
% /Applications/Mail.app/Contents/MacOS/Mail; exit
dyld: Symbol not found: _DeleteSeenPOPMessagesCompleted
Referenced from: /Applications/Mail.app/Contents/MacOS/Mail
Expected in: /System/Library/Frameworks/Message.framework/Versions/B/Message
Trace/BPT trap
logout
[Process completed]
In contrast to this, when I navigate to the same place starting from OSX 10.4.3's Mail 2.0.5 (Mail --> Package Contents --> Contents --> MacOS --> Mail) and double-clicking Mail launches Mail 2.0.5 immediately and produces a Terminal window that says the following:
% /Applications/Mail/Mail\ copy.app/Contents/MacOS/Mail; exit
Is there something I can add, subtract, modify or tweak to allow the older version of Mail to launch and run under OSX 10.4.3?
Thanks in advance...

It's not the new look I dislike (much), and I do not need assistance managing my mail.
What's bugging me is the grossly reduced functionality. I can't choose whether the mailboxes are to be on the left or the right; Apple has decided I didn't really want them on the right, even though I foolishly thought I did. I can't reliably selectively delete text by highlighting and hitting [delete]; Apple has decided that when I do that, I really mean to delete the entire line of text and not just the selected words. I can't start with a narrow search (only in a particular box, only in a particular part of the message, for instance) and widen it as needed; Apple has decided I always want to start with the widest possible search and narrow from there. Very, very obnoxious: I'm smart enough to have a good enough job to be able to afford several recent-model Macs, but Apple feels the need to treat me like a six-year-old and not trust me with the ability to make my own decisions about how my own machine should work. I cannot find a single, solitary thing that's better or easier about Mail 2.0.5 than in Mail 1.3.1.
