As an early adopter I know that I’ll stumble into bugs and problems in Apple’s newest OS. The first I’m come across stems from Safari’s integration with Twitter.
Note in that in image on the left there is no ability to cancel a tweet once you click send. I suspect that I’m running into this problem because Twitter is presently (at the time of this screenshot/writing) experiencing downtime. Regardless, the inability to cancel the tweet is particularly inconvenient because the send tweet window hovers over all Safari tabs (as seen in the right-hand image).
This persistent hovering means that if integration with Twitter stalls then Safari ceases to be a useful browser until the send attempt times out. Ideally a future patch will link the ‘send to Twitter’ window with the specific tab the tweet is being sent from, as well as ensure that users can cancel tweets at all times. Hopefully we see a point upgrade soon, to iron out this and other bugs that are being reported across the ‘net.
