@sgunhouse I do use the open all at once for other bookmark areas so I'm familiar with how that works but I'm not using the "Open all in new window" command in this case so I don't think that applies here. I'll explain in more detail...
I have one subfolder of bookmarks that contains four entries in it. Each of the four bookmarks in there browses to a link that then triggers an email to be sent by the server that you browse to. Theoretically, when you click on one of the bookmarks, only that link should be followed and, therefore, only one email should be sent. That's how it worked when I was in chrome (where I imported these and the rest of my bookmarks from). In opera, if I click on one bookmark, I get all four emails as if I had clicked on all four bookmarks one by one.
I figured maybe opera was loading the others in case I happened to click on one of them next. I just can't figure it out. It's starting to get a bit annoying and it's the only issue I have with this great browser. Very confused over here...
