Fog is running perfectly for now.
The only issue is that when I take an image the task is shows as queued even as the task is running. the only way I can be sure it's running is by watching the space used increase after refreshing the web admin....
This is no help at all, but mine does exactly the same.
Isn't this a known issue with certain versions? Mine does it at the moment but as you say, I just keep an eye on the used space increasing.
If you refresh the page, it updates though doesn't it?
