CSS Menu Messing up Design Page in CS4

The menu was created using my DW8 machine. It has worked very well for 2 years. I've just moved local site to a new laptop which has Dreamweaver CS4. All is good except the CSSMenu.
The CSSMenu does not render in Design view. It blows apart the rest of the page and hides the rest of the page content.
It is placed on the page as an SSI. The inlcude file itself works fine. CSS Menu Write works fine. It's just when it is included on another page in CS4. It looks fin in Design view on DW8.
Anyone have a good answer?

there really isn't a good answer to design view issues in Dreamweaver.


Design view is not as robust as a web browser. It can really only be used as a rough guide, and will frequently display incorrectly.

the real question is:
does it display properly in the web browser?

Thanks Jason,

That doesn't really help me when I'm simply trying to edit the content area, and the content area has dissappeared and is not editeable in design view. The workaround is that I have to disable the SSI filename, refresh, make my changes and then repair the SSI link.
Is there a way to turn off SSI content from trying to render in display mode in CS4?

In the Dreamweaver preferences, you can try to uncheck the "Show Contents of included files" option in the invisible elements section.

Jason,

You are the best person in my life today!
I must have looked at that checkbox on the Invisible Elements Preference page about 6 times and never really saw it.
Thank you very much for your help!

you're welcome.
