I don't know if anyone else has seen this, but I'm using Google Chrome on a Mac as well as WP version 3 and Atahualpa 3.5.3, and I was trying to upload a settings file for my webpage using the Import/Export feature in Atahualpa 3.5.3, and every time I tried, I would select the file and nothing would happen. I could refresh a page on my website and nothing would change. After banging my head on this for a while, I decided to try it using Firefox on my Mac, and voila, it worked just fine.
I have no idea what's causing the issue, Chrome or Atahualpa, but I thought I should let the issue be know just in case, especially since I use Chrome a lot these days and would love to see the issue figured out at some point.
Thanks!
