Using Democratica with 4.6 (actually, civicspace 8.3), with two-column layout, I've had an issue with IE (only tested on winXP ver. 6).

If the window is quite small, and then resized to maximum, the left hand column doesn't get redrawn and is left overlapping and obscuring the main column. I tried finding other references to this but couldn't, so here's my solution:

1. Add

onResize="ResizeIE();"

to the body tag.

2. define (the javascript function) ResizeIE like this:

function ResizeIE() {
  if (navigator.platform == "Win32" && navigator.appName == "Microsoft Internet Explorer") {
    if (25 > (screen.width - document.body.clientWidth)) {
      if (25 > (screen.height - document.body.clientHeight)) {
        window.location.href = window.location.href;
      }
    }
  }
}

What this does is reload the page whenever Internet Explorer is maximized.
