Hi Rick
Thanks heaps for the screenr link, that works great. I think I may have worked out what is happening. Our computer environment is a Citrix environment, this zoom issue seems to be happening when I am outside that environment and the laptop I am on does not have Java - the htm and swf file need to reference to the js file to play correctly - I think this may be why. I'm in the process of getting Java onto my laptop to see if this fixes the issue.
When I do the screenr in the Citrix environment the files play fine.... unfortunately I can't do the screenr outside of Citrix as I don't have Java on the laptop... !
If it doesn't I'll come back to you
Many thanks, much appreciated.
