strange scroll on iOS

[Ludovic Thébault]

Hello,

I've created a field to display a long list. I can scroll with a native scrolller on iOS ( iphoneControlCreate ...) no problem, it's work.
Because the list is very long (>2000 lines) i've create an alphabetic list to go directly at one letter.  It's work also.

But for example : in the main field, i scroll to the first lines  which starts by a "B", then i use the alphabetic field to go directly to the lines starting with a "P", the main field scroll to these lines, but when i want to scroll again in the main field, i restart instantaneity to lines "B".

What i miss ?

Thanks !
