Hi pwkpete, I've not yet tested under 5.7 though it is set in the marketplace to deliver the latest version to newer releases of C5. I will look into this in case it's a quick resolution on the marketplace settings.

Having just checked, you'll need to use Calendar Nav for 5.7+ which was refactored to work with the changes in V5.7 and supersedes the old free version which is possibly what you're on in earlier versions of C5.

Thanks! I didn't see that in the search results for some reason... (ahh, because it wasn't in the free list - I'm doing this as a freebie so was focusing on cheap :) )
