Jerome,

I just created a very crude example. It is just to prove that nested scrolling 
groups could be put into other scrolling groups and that the nested could be 
restrained to vertical scrolling and the main group could be restrained to 
horizontal scrolling. This works.

Here is the link:

Now to make this work for you I would put a UINavBar at the top inside of the 
main group to script scroll left to right and back again. Then I would further 
the nested scrolling group script to make scrolling work from within the text 
field as well as the back ground (try passing mousedown maybe). (check out the 
options field which does that on its own.) Then I would make a separate little 
popover arrow that set itself to the side of the main scrolling group and 
positioned itself where ever the main car is clicked.

I didn't want to do it all for you but rather just show you how it can be done.

HTHs
