Google not cacheing new pages

Since 2 weeks...

Hi

This is the first time I have seen this. Google has consistently been indexing and adding pages to its cache for my site almost every day. However, it hasn't done so for about two weeks now. My PR is ok and my baclinks have gone up. It still visits every day although it seems only the home page?

Any suggestions what might cause this?

Thanks
