I seem to be having a slight problem, the installation goes smoothly, then i can view the sample site with the sample data etc installed all looks good. Then random pages seem to stop half way through, i mean say a page has 15 lines of text & footer the page only shows 10 lines of text and the footer doesnot show, then if you refresh the page or goto another page then back to the previous page the page will show correctly.

Has anyone else had this happen? How should i proceed?
Attachments show an example of a 'cut off' page after it was displayed i clicked to the home page then to How CMS Works / Workflow & the page then displayed correctly. i have added a further screengrab of a project i have just started, this site has 6 pages with no pictures just text, just standard pages / sub pages but the same thing seems to be happening. Any assistance would be greatly appreciated.
