Okay, so I wanted to use the Most-Viewed Products report tool today and I see it has been "improved" and that it now has a date range facility.
That's cool. It's default is a one month period from the current day and 30 days prior. The problem comes when you attempt to alter the dates. The new date settings only remain for the first page of results then when you click on page two they revert back to the default of one month.
Is this a known problem? I thought it may have been a problem with Safari (Mac) as it does have a habit of throwing up some odd issues, but I tried it in Firefox and found the same problem.
Cheers, John.
