I've been trying for a few days to trace a bug in my blog. What happens is that, in Internet Explorer, if the top entry on a page has a photo before the text, then the title of that entry vanishes (though can be put back by highlighting then unhighlighting).
I'm now pretty sure I've tracked it to Internet Exploder being incapable of handling the innocuous "display:block;" style element under such circumstances. I can't see any sensible way round it as it's in a bit of code which appears automatically when I insert an image and I'd have to edit it out manually every time.
So sorry, and I blame IE. Use Firefox - it's much better!
