Testing with latest NVDA snap and 2011.2, firefox6, 7, 8, and 9, (32 and 64 bit), Chrome 15, IE8. This happens in all machines I've tested (xp, Vista, 7).

This is only a problem when "Automatic focus mode for caret movement" is checked in the Browse Mode dialog. With this disabled, all works as expected, NVDA will read the top line of the edit field and all is well.

After typing a few lines in a multiline edit box, then hitting up arrow several times to go to the top and eventually pop out of Focus Mode, NVDA just repeats a line two or three down from the top of the edit box, or it will say "edit multiline, blank".
Example:
Go to any multiline edit field and paste the following text

this is the first line
Here's the second line,
And now the third.

Expected: when you start arrowing up (or pressing ctrl-home and then up arrowing), NVDA should pop you out of Focus mode and let you review the page above the edit box.
Instead, NVDA will just say, "Here's the second line" or "blank"
