Javascript Zoom Test

You should be able to switch between fixed and variable zoom exploded diagrams. I struggle with browser Javascript compatibility across the various browsers, so the variable zoom facility will probably work if you have IE50 or higher, possibly work if you have NS45 or higher, or Opera 7
I have run a test below, if you see a RED RECTANGLE with the legend ZOOM CONTROL then you should be able to zoom the sample diagram (try it). If you get no red rectangle then the variable zoom is not working, you may get "page not found". The complication comes when you want to scroll the diagram to focus on a particular component, then the zoom control needs to "float" in the top right hand corner regardless how you scroll the diagram, else the zoom controls are off picture!
If zoom is not working then you should choose "fixed" rather than "zoom" for the diagrams. If you select zoom and it does not work then no damage is done, just reselect the "fixed"
