Well, I've never seen this happen despite using NSScrollView extensively.

So that suggests that there is something a bit strange with the way you're 
creating it, or setting it up.


In IB, you can either add a scroll view than add a custom view to it, or add a 
custom view and then use 'Embed in Scrollview' to wrap it in the scrollview. 
Both work fine for me.

The next thing to check is the sizing settings. Are you using classic springs 
and struts or the newer constraints? I'm afraid I don't yet have any experience 
with the new thing, only springs and struts. The scroller should usually be set 
to expand and stick to all four sides of its enclosing view, but the custom 
view within is usually of a fixed size, and this might change programmatically 
according to your content. There's no reason to change any other setting, such 
as the scrollbars or the clip view of the scrollview.

Whether your custom view is flipped or not will affect the way the scrollview 
behaves - something to check.

Does anything in your code "fiddle" with the scrollview? There is rarely a need 
to. Have you subclassed it, and overridden something like -tile?

You could try starting a fresh project and quickly trying to put together a 
simple scrollview without any special code and verify it works, then look for 
what difference there is in your project that changes that.
