Rendering issues

I have set up dhtmlxScheduler on my dev machine, but I am unable to get it to render properly.
I have just the css and html required to display the scheduler and nothing else. The issue appears in both Chrome Version 25.0.1364.152 m and MSIE 9.

As a picture says a thousand words, here is a screen shot of my problem:-


As you can see the navigation line is too low and the table lines do not line up on the left hand side.

Has anybody come across this before?

If anybody else has this noob problem then do what I didn’t and read the manual page here.

Be sure that

a) you have included ext/dhtmlxscheduler_dhx_terrace.js
b) you don’t have any other css on the page, which may redefine global TD, TR or DIV styles ( custom css is not a problem while it doesn’t redefine global tags )
