If I have any 'main site' talk page open and then click on local it now opens the local site in a new tab (which is what I want it to do) but it also reloads the page I'm on (ie the mainsite board/talkpage) as the local page as well. I end up with two local tabs - the newly opened tab and also the page I was originally on. It happens on both PCs I use although interestingly if I 'middle click' to open local in a new tab it just opens the new tab and leaves my current tab as my talk page...
...does that make sense?
