I am using SDL Tridion 2013 SP1. In Content Explorer context menus were not opening (I am trying to install Content Porter but Tools menu is not opening). I am using IE 10 and I have configured IE as explained in here, but still it is not working. Can any one help me to fix this issue. Thanks in Advance.
Internet Explorer's Compatibility Mode has caused issues for me. Even when not set intentionally, I believe IE's default sets
Display intranet sites in Compatibility View, which likely applies for most SDL Tridion setups.
In IE 10 this breaks a few things in the Content Manager Explorer including the Tools tab and Ribbon Toolbar buttons in form view. Try unchecking the option in IE under Tools > Compatibility View Settings then refresh the browser.
