Thanks for the reply. Im guessing you are on a MAC?
So mine was in a slightly different place but wow what a pain to change :)
Windows Vista would not let me save over it so in the end had to save a copy then delete the orginal then rename copy.
Windows just reports the file as not exsisting.
Once done it works fine I notice in DW the behaviour now has a WA added to the delete file.
Thanks for the help.
