If you're using Firefox, bring up the Options dialog and select the Content tab.  Click on the Advanced button next to the Enable Javascript checkbox.  In the Advanced Javascript Settings dialog, uncheck the "disable or replace context menus" checkbox.  This will prevent web pages from disabling the right-click context menu (it will still pop up a "Right-clicking is disabled" box, but when you click the OK button, the standard right-click context menu will then appear).

If you're not using Firefox, then I can't help you.
