I haven't been able to track down exactly what's causing this, but I'll describe it anyway. I've noticed when refreshing a tab (Cmd+R) or reloading the same URL (Cmd+L, enter) that occasionally it will go to a new, different page I have recently visited in another tab or window. I'm pretty sure it's started happening in the last couple of weeks. Has anyone else seen this?
