And now it's working properly again. I don't know why it's working now but it wasn't when I wrote the original post.
I have a very long quick launch tool bar so putting new icons into it is quite simple but when I tried originally it didn't matter where on the quick launch bar I tried to place the item it always showed up with a tooltip telling me it was going to pin it to start8 menu. Maybe the computer needed a reboot, I can't remember if I had installed the latest Start8 menu that day or not.
Anyway, seems to be working the way it should again, so it's all good now.
