What Explorer do you use?
Some options,
1) your explorer might be outdated. Look for an update and install it.
2) Your explorer security settings might be too high. Some of the frames are trying to perform operations that the explorer hasn't authorized. For example, download pictures to the drive, retrieve pictures from your drive (you can get some computer information thru this method, that is why some browsers don't allow it by default), or the page is trying to run scrips.
To check this, you could try taking note of the security settings you currently have and see if you can change it to medium, and try to see if that works.
3) try installing another browser. From your nick I gather that you are using Mac. Which version? Or you are using other OS?
If you are using Windows or Linux you could try any of this browsers Firefox, Mozilla, Opera.
