Since the last update I noticed this: (see pic, and one time scaled up) I noticed this in both Firefox and Safari.
It's not significant but I never saw this before since last week and I thought I'd let you know.
Also I'm experiencing a bit of a challenge when attaching a picture to a post. Apparently the only way it works for me is by using the basic uploader. And even then I'm not sure if it's spot on 100% of the time.
I don't know if it has been said already or if someone else experiences the same, but just to inform.
In this post too I tried to upload a picture. I'm not sure it worked though.
