Objet : Re: Air Stage Text Issue

I can try to ask the engineer who worked on it to see if he remembers, but I would guess the

1) There was hope that AIR would provide a solution
2) I'm not sure proxying would handle text selection.
3) I'm not sure proxying would handle partially occluded text inputs.

You're welcome to take a shot at it.  Adobe generally didn't like half-baked solutions so
if it there was no solution for partially-occluded text inputs it wouldn't provide a solution
at all, but maybe it is worth offering a solution for folks who won't ever partially occlude
their text inputs (which is probably a lot of folks).

But before you go work on that, can you look at the most recent mustella failures?  I think
there is a new DataGrid failure.
