Unable to move web part

I had an error with not being able to move webparts from in a page. Something like this:



After a bit of research I found the the problem was related to web part zones having a relative position in the CSS. See http://www.sharepointblogs.com/tmt/archive/2007/11/01/CSS-causes-JavaScript-error-while-moving-Web-Parts-in-edit-mode.aspx .

There are a few ways mooted online to fix this problem, but the best solution for me was to set the position of body css element to relative also:

body
{
    position:relative;
}

Problem solved...
