I'm having loads of problems with the pop up form to add or edit an entry. The toggle sidebar takes the iframe to the sites home page, so does the cancel button but on some browsers such as Chrome doesn't work at all. In Internet Explorer (8) I'm getting the following error if you click the x to close the modal window instead of the cancel button.Message: Can't execute code from a freed scriptLine: 1Char: 32179Code: 0URI: plugins/system/mtupgrade/mootools.jsI've installed firebug but I don't understand javascript at all :( but this is what it says:a.implement is not a functionLine 1MooTools.upgradeLog is not a functionLine 1MooTools.upgradeLog is not a functionLine 1tinymce.util is undefinedLine 1tinymce.util is undefined/plugins/editors/tinymce/jscripts/tiny_mce/tiny_mce.jsLine 1
