In the file useragent.cfg in the directory
<intrexx>\client\cfg, the user agent rules currently
defined on the client will be written in the following form:
<userAgents>
<userAgent guid="Guid of user agent"
regEx="regular expression" description="description
of user agent" lock="true"/>
</userAgents>
If the user agent rules of a layout are edited on other clients in the
meantime, differences will result here in the configuration. In the
lower area of the message dialog, you can decide whether you want to
apply the rules as they are preset on your client in the file useragent.cfg,
or if the rules should be applied from the layout in your
client configuration.
