In Excel, NVDA often decides that you haven't moved, even when you have

Sorry for the poor summary. I couldn't think of a good one that conveyed this concisely.
In Excel 2010, when moving across an Excel spreadsheet, NVDA is periodically deciding that you haven't actually moved. It will read the cell you just left instead of the cell you arrived at and will continue to insist that you are on the cell you just left in every way. It seems to detect that you tried to move, as it does reread the cell. I haven't been able to narrow this down to a specific procedure. Sometimes, it doesn't happen. Sometimes, it's so bad that you can only effectively read every other cell. It isn't a specific spreadsheet, and it happens on both my computers. For me, this happens with 2013.2 as well as the next branch. I'm using Excel a lot for college, and this periodically renders it unusable. Restarting NVDA sometimes helps, but sometimes does nothing.

I have seen this a little. But to clarify, if you move multiple times, surely you stay one cell behind where you are, you don't stay stuck on the very first cell right? E.g. you're on A1 and you press right arrow. It says A1 (should be b1). You press right arrow and it says b1 (should be c1). Or did it still say a1?
Clearly we need to wait a bit longer before grabbing the current selection again. Perhaps we can employ something similar to caret movement where we keep checking with a time out.

That seems to be correct. I've had that a few times, but whenever it starts I immediately fiddle with it until it stops so I don't actually see that often.

I'm encountering this on windows 8, Office 2010, NVDA 2013.2.
Notice how the following log skips G24 until I go back to it. I can't get this to happen reliably, but it happened quite often yesterday.

Please test the following try build:
http://community.nvda-project.org/try/t3558/nvda_snapshot_try-t3558-9641,338b7bc.exe
Please test for a good while and let me know if the problem goes away.

I'll do so as soon as possible. I can probably instal it tonight. I'll poke Tyler as well, in case he doesn't see this. Fortunately for this ticket, , I use Excel all the time. Testing is not a problem.

Replying to camlorn:
Any luck with testing this? does it improve things?

Sorry, life got busy. I've been on it for the last 2 and a half weeks and It appears to fix it. I don't use excel extremely frequently, but I do use it for my physics lab reports, and it works with no issues. Doesn't seem to break anything else. I suggest incubation; it seems fine, and needs wider testing than I can provide at this point. Unless you wish me to test it further, I'll be over on next again.
