Issue with healer running to tank randomly

So I got a 5 man team, I am currently at Pally 75, shaman 75/76/76 and Priest at 74. The issue is as stated above the healer just loves to run after the tank but non of the others do so I am unsure what the deal is.
My setup: Octopus, Addons Jamba, single 24" LCD with main at full and the drones at the corners running on smaller windows.

Macros/Keybindings/keys:
1 attack (on the tank only)
2 DPS macro (on all toons even the healer which is one of the buttons I press and she runs at me and starts following.)
3 Healing macro (used on healer+1 shaman for when I need that extra healing, normally shaman is casting some kind of dps so she will not always cast a heal)
4 Totems
5 TS, Aggro control for pally
6-0 Reserved for tanking (0 also cast PW:S on tank)
-,[,],= various buffs

f Follow macro/target what tank is targetting/assist
e accept macro/invite group
Shift+Q spread out macro
. priest/pally mana regain spell
Shift+y drink

Num 1-4 some extra healing buttons for the priest mostly and some shaman chain heals as well

So like I said I just start dps'ing and all of a sudden here comes the stupid priest running to me and following like if I had pressed the follow key, the reason I am posting this is because I have been trying to do DTK and the pull of the guys that do the black AOE circles is impossible if I keep getting the healer killed because she just decided to follow me.

So any thoughts? Feel free to tell me I'm an idiot and that its a simple fix, or ask away some more about my setup, not at the computer right now where i have it set up or I have more, that and I have stupid Spyware 2009 malware issue that I need to get off my computer before I take a gun and shoot the computer dead!

Only thing I can suggest is find a nice clear safe area and then kinda go thru the motions so to speak. hit all the keys one at a time.

Dosen't jamba have a thing that pulses autofollow?

Yea, its probably a condition with jamab's strobe following function. How are you setting follow between the characters? Do you have 'Pause Strobe During Combat' options enables, not sure exactly the naming. I have a similar issue with my Shaman/Paladin set, post-combat my shaman will be tossing a Lesser Healing Wave to top off the paladin and the follow pulse hits and she walks out of the heal (interupts).

type /jamba go to Jamba-follow and make sure auto follows are all off on all your slaves. you probably have it turned on your priest.

or you have one of your DPS keys macrod to /follow on your priest, so check all the keys you press while DPSing while watching your priest window and see what triggers a follow.

I thought about the same thing, I checked the follow strobing option to see what I had set and I checked all the stop follow strobing options, so its checked to follow upon ending combat, but it should not strobe at all if anyone is in combat and the rest of the options as well, its just strange because all the others have the same set up other than the macros. I will check the macros later I did not get much of a chance to get on last night since i was cleaning up my computer and I had a headache. I was just thinking I clear everything from the healer and start from scratch and check all her macros and see if I accidentally put in a follow in her cast sequence it almost seems like she has it in castsequence which I am not sure if you can have that as part of the cast sequence any one ever try to put in a cast sequence and slap in a follow after a few spells? Well I will try it and let you all know if it does work, I would think that it should but not sure.
