Do you get a prompt that asks if you want to continue listing containers after the first 100?
No all that happened was the downloading spinner kept flickering on and off. If you are going to the 100 at a time listing, the same way Rackspace does it, then it becomes unusable as I have a couple thousand containers. Clicking "continue" after each 100 would mean that I would have to babysit the download and click twenty times to get a complete listing.
We cannot reproduce the issue that no prompt is shown to Cancel or Continue when listing all containers. When choosing Cancel, it will display the first 100 containers in the browser. Set the container you want to access in the Path bookmark setting to connect directly to the container without listing all containers in the account.
Sorry but "worksforme" is rarely an actual solution. Did you create an account with a couple thousand containers?
Also, crippling the download is just an admission that your new release has issues that you will not fix. I am using 4.4.5 which works fine while 4.6 does not work. This leads me to believe that there is an issue with 4.6. I will even privately send you a login to our account so you can see the problem in action.
