Internet javascript/Printing problem

When trying to activate some buttons on internet sites I get the error message at bottom of screen "javascript: void(0)" and nothing happens. On other buttons the message is not seen but the buttons do not activate. Many buttons activate as normal. Another feature is that I cannot print from the internet, or from email messages. This was my first indication of a problem and I determined the javascript problem after persuing it. I have reloaded AOL software and printer software to no effect. I guess I could reload Windows XP but only want to do that as a last resort/

Anyone have any ideas.

 

AOL - that the problem. Use IE6 instead.
