Thanks TIG,
This is very usefull. You need to understand than I'm British but dont do Imperial, like the rest of us (officaly). But when I come across a source document that is Imperial its good to visulise the result in both formats.
Request 
To go the extra mile(kilomiter) the Imperial output could be in feet and inches rather than decimal feet so I can close the loop on the original document - check to be sure,to be sure.
Thanks Again.

By "edit window open" I meant the main program window.
After my last post I discovered that it was the (annoying) start-up splash screen that was appearing off screen. Once I moved my 3rd screen around I was able to find the splash screen and move it to where it would be visible.
Good idea to include image but I don't have a web server so I cant reciprocate unless there is another way?
I forgot to mention for those interested that my setup is a Thinkpad W540 with a Zotac Display port (Thunderbolt) to dual HDMI adapter to 2 x AOC. (Asked for docking station!)
This configuration seams to be very stable and was easy to setup BUT it seams to completely bypass the NVIDIA graphics accelerator. So when we get off the ground may have to invest!
....unless you know otherwise!
Here is the solution I found, sou I thought Id share 
SU14 it seems dos'nt like displaying off main display. Which was a hint given by CF. Thanks
I changed my dual screen to be the main display (start menu etc) This could come to bit me when I return to single screen!
I started up SU which appeared on dual display eventually. After selecting SU in start bar nothing happens. Then start bar SU icon becomes highlighted. When hovering over the ICON the instance running icon appears, but no program. When I instruct icon to close the non running program starts.
I then enabled the floating windows. Some where selected but not to be seen until I enabled the outline window which I usually set to be screen depth. It was located in virtual space above my dual screen and overlapping the top edge. So now a had a clue to where this and perhaps the others where how to retrieve them?
In the Screen resolution settings (right click screen)it is possible to move the screens around relative to each other by selecting the screen icons and dragging them. I moved the laptop screen above the dual and there they where.
If you only have 2 screens then this may not be possible as I cant see on my system how I would split the dual extended display and turn it into 2 floating displays.
Hope this helps any others suffering the same random behavior.
These suggestions helped to an extent but I am still restricted from laying out the windows as I would like.
I have 3 screens. 2 Identical External screens that are set to behave a one screen. and the native laptop screen.
I can get the windows, (layer , outliner etc)to stay where placed if I close the template without saving. So thanks for that tip.
However I am restricted where I place them. I have the edit window open in the left External display any can put the windows (outliner etc) on the left edge of the right external screen (middle). I would like to move outliner onto the right of the right screen but every time I attempt this the window will drop onto the native screen. They seem to only exist happily on an external screen if they are stuck together.
Nice screens, no help!!!
Any other experiences that might help please. 
Id like to be able to mouse over a vertex and be able to read it's x,y,z coordinates and have the potential to edit them. If this is already possible then id like to know how
My pet hate is the tool menu fiasko 
Some sort of rules for nameing and sorting would be nice. Perhaps the index icon of the tools set could also provide properties and be the "placeholder/roleup" for the tool set. I need to be able to use more of my screen! And not have to play 52 icon pickup every time vista starts SU with a small window.
I am particularly happy to recently discover FAK which answers a question I asked a while ago about making threads. I would propose that it replace tha standard follow me which never made sence to me (adding incrementing angle to horizontal with rotation )unless someone could explain!
Thats my 2p worth.
Thanks Guys
I have installed and reinstalled SP3RC1 several times and even created a "clean" install of SU7 but cannot get a Joint settings panel to appear from either a right click properties selection or from the pull down menues. Any ideas please?
