True. The last version that shipped with WB2.05 was updated (more parameters) over the version that shipped with WB1.3.
I don't know for certain which version is now included with the BetterWB enhancement, but, I think it is the 2.05 version. Thanks Gulliver!
NOTE TO ADMIN!: What has happened to this site? Posting & editing is difficult now. It's hard to log in and then the site logs me out after just a few minutes. It's very frustrating!
