Ok so, would be grateful of any feeback on this Safari issue. If I have a window open in Safari and minimise it to the dock, then open a new window, the new window doesn't show up. If I go up to the window menu it shows as being open but again if I click to select it it doesn't show up or take me to the window. To add insult to injury, if I then switch between spaces, said window will show up for all of a second as the transition between desktops happens then disappear again. I'm guessing it's a known bug and will be sorted but would just like some peace of mind that it's not my machine having a laugh. Cheers.
