safari not loading useful popups

safari didn't do this before but now it's not able to open up those small windows. they're not exactly pop ups but just useful little windows that appear if you click on a link. for example, some sites have a 'contact us' button, and if you click on it, a little window box opens up where you can type your message and all that. my safari can't load this and i'm not sure how to fix the problem. checking or unchecking the popup ad preference in safari doesn't do anything. does anyone know the solution? thanks!

 

nope...javascript is enabled and i repaired permissions...didn't do anything.
thanks for your suggestions though.
