If some of you have upgraded to IE 8 and get a warning error on the PINSTACK site about "Cross Scripting" you can ignore it.
I installed IE 8 on my PC today and got the same error. I then looked into the source that was generating the Cross Scripting error and found that it is "NON-MALICIOUS"
Now with that said dont ignore that message on other sites....it's best to contact the owner of the site and ask them why and what the site is trying to Cross Script...
For more info on Cross Scripting see Wikipedia
