Mail preview not working any more - Mountain Lion
Ever since I upgraded to Mountain Lion - the preview is not working in Mac mail properly. So the first email in the list that I click on shows the preview but when I click down to any of the others in the same mailbox - the preview does not change. The only option I have then to see what the email is all about is to double click the email and look at it in its own window which is really annoying.
Any ideas anyone? Yes I do have all the software upgrades installed and am on the new Mac Bool Pro Retina display...
thanks
OS X Mountain Lion (10.8.1)
