im not sure that im right here, but i hope...and i hope you understand my english .
I updated today to 3.6.7. Now my "Tag-Cloud" miss the line break/break -> http://www.pixelfeuer.de below "Schlagw÷rter"
That Tagcloud is "SimpleTag" but with the default Cloud-Widget it is the same problem. That bug/issue isnt into 3.6.4. This missing line breaks (whatever) are seen within firefox, opera, chrome, IE.
