I’m using a dataview web part, and have set one of the columns to be a link using the formatting tools. This works just fine! However, when I try to set a target for the link of _blank (to create a new browser window and open the link in that), well, the page doesn’t save correctly. No _blank is put into the links, and you have to reload the page in SharePoint Designer ‘cos it’s gone funny.

Again, I’ve not got a solution to this – although the customer in question might not be using SP1 yet.
