So today I went to add someone as a friend so I searched their profile and hit the Add friend button add the top. When the page refreshed, I noticed that the profile views had gone up by two, not one. To be sure that it wasn't a coincidence, I refreshed the page and the profile views went up by two again. Then I clicked on someone in the online list, which opens the profile in a popup, and hit F5 to refresh. The views only went up by one. So basically if someone opens your profile in a normal window you get two views, but in the popup you only get one.
Just thought it was an odd glitch that I would let the NS guys know about.
Oh and I'm using Firefox 3 on Windows Vista if that matters at all.
