When i click links in this forum, it does not open up a new page but uses the current open page. This is one of the few forums that work this way. I tend to close links with pictures and then have to start all over again, logging into lustria-online, etc etc.
There are two ways you can avoid this: Hold CTRL when you click. Use the Middle mouse button to click. Both open the link in a new tab.
I am fairly sure that the middle mouse button only works on firefox, but I don't have a new version of IE so not sure if they updated that. But yes, I always use middle mouse button to open new windows. There is a switch in the admin CP where you can make a left click open a new tab/window, which is why a lot of other forums are like that, but it is up to Sammy on that point.
I am still using IE7 (I need it to compare the differences between browsers for web dev) and you can middle mouse click. I am not sure what version it was brought in. Perhaps it was this one? Middle mouse is a handy thing to know. Its right up there with Alt-F2 to rename stuff. You would be amazed how many people go through life not knowing that and waiting for the text to highlight after clicking or double clicking a file.
