Hi All,

I am using ExtJS 4.0.7 Grid which gets a couple of hundred records from server in JSON.
I find that there are two different functions to regulate the Scroll on the grid.

Whats the difference between invalidateScroller() and determineScrollbars() ?
I see that some times scroll does not work even after calling invalidateScroller().
However i don't know if its just luck or something else but determineScrollbars() is more efficient.
