I have V2.56r running on 64-bit Windows 7. The watch expressions are not updated unless I enter them with a right-click. If I enter them into the field with the black arrow, there is unreliable update. It might update a couple of times, then turns itself off. But mainly it stays off. Similar to this post: [SOLVED] [Ozone] 2.56M Possible regression with Variable Refresh The above post says problem solved, but I see the same problems.
