Whenever replacing or orienting a view, NX performs a 'Fit' operation. This can cause issues with attempting to resize the view to the last saved state.
Solution
This behavior is controlled by a customer default.
Use 'File --> Utilities --> Customer Defaults --> Gateway --> Display'
On the 'Miscellaneous' tab are options to control how NX displays the scale of replaced or reoriented views.
