Hi,

>Ok, I change to Environment.NewLine, though this is now a minor point when I have bigger problems - site doesn't work in FireFox, I get Service unavailble when I try to test on the live server and with my credentials I now seem to unable not re-start IIS.

Don't think I can be of much help here. I haven't worked with ASP.NET for about five months (and then it was almost exclusively web services stuff).
Do you really mean that the *site* doesn't work in Firefox or that a specific page doesn't work? Has it *ever* worked with Firefox? Maybe the problem lies with your browser configuration (or the browser configuration that ASP.NET is configured to work with)

>Also there is a visual appearance problem I can not figure out how to solve. In one of the columns in the GridView the textbox is out of place (e.g. lower than the rest of columns). I don't know what to do.

You could try examining the source markup for the page - maybe there's a style setting or something causing this.
