At the risk of being the odd person out, I thought I'd maybe see what folks' experiences have been in using BibleWorks to work through the Septuagint? I couldn't find a whole lot about it after a few forum searches ("Septuagint," "LXX," "Old Greek," etc.). But I'm sure more than a few BW users do utilize the Septuagint and its related tools.
I wrote a bit here about my experiences (all positive) in using BibleWorks to read through Septuagint text. (I'm still in version 8, but other than the fourth column and a Tov-Polak update, I'm not aware of LXX-specific changes in BW9. Of course, being able to see LXX manuscripts is probably pretty great.)
I'd be curious to hear others' thoughts and experiences... especially if there are some "senior members" out there who are getting even more mileage out of BibleWorks for LXX reading and study!
