Oddly, my problem seemed to fix itself, spontaneously. I do restart my computer regularly (I usually turn it off at night when I go to bed), but just leaving AW and coming back seemed to do the trick last night. Didn't even have to restart Chrome.
A couple other problems I've been having in Chrome also fixed themselves last night: the ctrl+F function hadn't been working right in Chrome for a few weeks, and a password-protected website I use for work wasn't letting me log in while I was using Chrome. Clearing my cache hadn't worked, and I was planning on making sure my bookmarks and whatnot were backed up and trying to re-install Chrome, but the problems just went away last night. Hmm.
I wonder if the issue I was having with AW was connected to the other stuff.
