Lots of web sites have disabled the right click function of the mouse button. It’s really, really annoying. This is done so that you don’t steal (via right-click->save picture) their photos or images or any other goodies. Unfortunately, it disables ALL right-click functionality: copy, paste, open in new window. So here is the simple trick to enable back the right click and allows you to use all the right click menu items.
It’s easy to change, assuming your using IE 6 or Firefox (any later version as well).
Click “Tools”->”Internet Options”
Click the “Security” tab
Click “Custom Level”
Scroll down to the “Scripting” section
Set “Active Scripting” to “disable”
Click “OK” a couple of times.
