Please Help Me Figure out what is wrong with this code? (Tooltip Mod)

[lilgulps]

Disclaimer
Let me first start by saying this is not my code, but the author of Ranttooltip

Why am I seeking help? Cause I am using an older version of the addon before he switched to his new layout system. The bug I am trying to fix has been around for quite a long time and it has become something of a challenge for me to try and just figure out what it was that caused it.

Needless to say... I haven't figured it out yet.

EDIT, I UPLOADED THE ADDON FILES IF ANYONE IS WILLING TO TAKE A LOOK

The Problem

Target line bug, causes the target line to continuously generate until the entire screen is filled up. Only exists if target changes targets while you are mousing over it. In other words, i mouse over subject a, subject a targets subject b, tooltip updates showing this. I am still moused over target a but target a now targets target c, tooltip goes berserk.

Examples
This is normal when you first mouse over a target, no target line created yet just the unit frame.
Screen 1:

Now I press f1 to select a unit, target line is created, still looking good!
Screen 1:

Now I press escape so that i am no longer targetting anything, tooltip updates but now the mana bar and health bars are skewed?
Screen 1:

I now retarget myself and the bug occurs at full force until i un mousover
Screen 1:

I don't exactly want to post a wall of text so i'll only post a small portion of the code here, if you would like the rest of the files emailed to you, to take a look, ask me and I will glady send the rest of the code over. Thank you
