Mobile Scroller with Snapping?

[Scott Rossi]

OK, I think I figured out the problem.  Apparently
mobileControlGet(theID,"vScroll") sometimes returns a decimal value (i.e.
10.5), but LiveCode doesn't allow setting the vScroll of a field to a
decimal value, so the field wouldn't scroll.  Rounding
mobileControlGet(theID,"vScroll") appears to have solved the problem.
