At times depending on the speed of the BOARD, IF I do an EDIT those swirls will show up that you are talking about and when I correct the post and hit edit again, they might still be there. SO, if you see them, I believe you can take your mouse click over the swirls and delete it. I think the post has to be in EDIT form though for that to happen.
It's just a thingy we have to put up with but not a harmful thingy...lol
WHEN you see those just drop me a PM and I will run to correct them for ya........Thanks
