Bl**dy formatting

Oh I dunno why it ain't working. I've been trying to settle upon what I consider to be the 'best' combination of template, font, font size etc etc etc and happened upon 'minima black'. I like verdana and have learnt that normal size is easiest on the eye. However, there are some formatting problems. Some of the earlier posts are all over the shop, line breaks all over the place. So, I look at the HTML, no line breaks, I swipe the text out into notepad and back into this blogger thingy editor, still no better. So I end up dropping back from normal to the next font size down to try and rectify - it performs some half assed correction, that, as it has gone 11pm and I have to be up at 6am, will have to do. I have also just discovered the 'blog this' button, well I say button....Anyway, I wonder what will happen when I press PUBLISH POST, not normal sized verdana I'll warrant!
