Hi Leo,
Thank you for your advice and ideas. Slowly but surely the vision I have is getting closer.
I have been working with the Internal Commands, and sadly I am unable to grasp the concepts that the manual provides. Following is the code I placed behind the buttons with a description of the results.
In the Find Panel, "show results in" has been set to "Source (new tab)".
Default Find Button
Close ALLOTHERLISTERS
Find
Wonderful, if I have my Custom Lister open and the Utility Panel closed, this little baby stops me spawning any extra listers. 
v1.0
Custom Button
Go TABMOVE=splitlister
I am so close to what I am after I feel a little giddy. A seperate lister populated with the search results. Now, apply my custom layout and its time for champange. 
v1.01
Custom Button
Go TABMOVE=splitlister
Prefs LAYOUT="FloatingFind" LAYOUTTHISLISTER
The way I have understood the documentaion, is, the FloatingFind layout should be applied to the current lister, which is the one I just created from the previous command. What actually happens is, a new Lister is created and FloatingFind is applied to my original Dual Lister. Hmm a little saddened. 
Is it possible to have Custom Listers displayed in the Drop Down that conatins Destination, Destination(new tab)...etc? Or a script that gets run when I push the Find button?
example pseudo-code
If CustomLayout <> Open
Then
Search
Splittab
Apply Custom Layout
Else
Search
End If
I hope that helps describe what my end goal is. I would like my search results to be sent to a Custom Lister that displays them in a way that I want, while I can still navigate and make search queries in my Dual Lister layout.
Again I thank you for the time and effort you have put into this Leo.
Stu.
