UPDATE: I just downloaded 2 WB's that had arrived as zips before. Now, not only does it show up as a .wba, there is the option to open or save it after clicking the download button. Awesomeness, guys, I've wanted that ability for like, forever! Whatever changes are being made, they are certainly in the right direction.
Thank you, web guys!!!
Looks like I'll be renewing my sub after all.
