I use the HTML option to enter my posts. What seemed to have just begun with 3.0.1 and continues with 3.0.2 is that it will randomly use a curly quote ( ” ) instead of the inch mark ( “ ) — it will also change a correct quote into a curly quote for no reason.
When that occurs, it breaks the code entirely, and since it’s almost impossible to see in the WP post entry page, I must copy the entire post into TacoHTML or BBedit (with color coded code) to locate the breaks.
There seems to be no pattern — it’s random.
