I cant Reply, Forward, or Compose in Yahoo email and I couldn't even compose this email in Community Forum on my Dell Inspirion 5100.  I can read my Yahoo email but can't send anything out.  When I load the page it gives an "error on page" at the bottom left and doesn't work.  When I click on the Yellow !, a box says:

 

Line: 798

Char: 7

Error: Access is Denied

Code: 0

URL: http://us.f127.mail.yahoo.com/ym/compose etc...

 

My hotmail editor works just fine, but not Yahoo or the community forum editor. I can run the Yahoo and Community Forum editor fine with other PC's, but not with my Inspirion 5100.  Any suggestions would be greatly appreciated.
