I think it could be because you are licking the bar - try clicking it!! Seriously though - try the below instructions (I'm assuming you are using internet explorer)
* Open the <Tools> menu
* Click <Internet Options>
* Click the <Security> tab
* The Internet zone will be selected by default
* Choose one of the following paths:
o Use your mouse to move the slider bar up and down to change your security level
o Click <Custom Level> and select each security setting individually
* Click <OK>
