I did a bit of web research. The below is from the Symantec Web Site:
Cannot see all of a Web page when (Norton Internet Security) NIS or (Norton Personal Firewall) NPF is installed Situation:
When you go to specific Web pages, not all of the page is displayed. If you disable some features of Norton Internet Security (NIS) or Norton Personal Firewall (NPF), all of the page is displayed.
Solution:
This problem happens when NIS or NPF has been configured to block scripts, ActiveX controls, Java applets, referral information, or advertisements.
ActiveX controls and Java applets can be blocked by customizing your security settings from the main interface. To find out whether this is the problem, see the section "Customized settings."
All of these security features (scripts, ActiveX controls, Java applets, referral information, and advertisements) can be blocked by specific Web rules. These rules are located in the Advanced Options of the program. For scripts, ActiveX controls, Java applets, and referral information, see the section "Web rules."
Customized settings
1. Open your Symantec desktop Internet security or firewall product.
2. Click Security.
3. Click Custom Level. The "Customize Security Settings" window appears.
4. Look at both the Java applet and ActiveX boxes. If either or both are set to block, lower the security level and then click OK. (In the example above, Java applets are being blocked.)
5. Try to connect to the Web page again.
Web rules
If elements of the Web page are still being blocked, there may be a Web rule that is blocking scripts, Java applets, Active X controls, or referrer information.
