This is a follow over from the previous version of SS...(post here http://silverstripe.org/archive/show/101576?showPost=238505)..sam suggested upgrading to 2.3.0 to see if the problem has been fixed - it hasn't been.
I only see this this in IE 7 - if I drag and drop a page to a new location in the tree and then click on it (to edit/publish etc) I get this error "Stack overflow at line: 0"
Does anyone have any idea about a fix for this? I have a client who is pulling their hair out!
