I have not seen that and I tried hard not to have any return before or after the [code] tag so that the code would be as in line as possible without wasted space. have a return after the tag would mean an empty first line in the code window, sometimes meaning you had to scroll instead of being able to see the whole code sample at a glance.
but the images not appearing at the right place, the heavy post compression that makes them blurred, the lack of colors have rendered many of my tutorials (in French section) totally cumbersome (some had tens of thousands of visits like this one on states machines or that one and many others )
I'm not planing on updating any of those (and even if I wanted to the posts are locked...), this needs fixing by the team writing a proper migration script when the text includes tags.
