Hi all. I googled this to hell a while ago... I found some posts about it somewhere with this exact problem, but I just can't remember what the reason was.. And I can't find that source for the life of me. These things only started showing up after I upgraded to SL, and after they appear, my mac will inevitably hang in 30-45-60 minutes give..or..take. They show up on ANY window of any application I will use. But, what is the reason for this? Attached is a picture of these little buggers in Firefox, as well as a maximum-zoomed in image of them in preview.
