Dateformat in IE

Hi, running through a lot of posts in this forum and R5 forum, we have not found anything that addresses this issue directly. We have set up all the registery settings correct, and enabled the correct date format for our environment. The server is running as a service under windows 2003. DD/MM/YYYY, server console shows the correct dateformat and so does the browser… in some cases. It seems like the IE 6.0 browser option (internet options) General - Languages, One can switches between ie. Danish and English, and the separator in the browser changes from / to -

This is not so good as we would like to have a consistant date format regardless of browser settings.

This can be forced by setting the datefields on the form to custom and specifying a / as separator, but for computed text fields you cannot.

Does anyone know of a server setting or ini setting that supresses the IE 6.0 setting and uses the server setup, for dateformat, in all cases.
