Yes, there are a couple of known problems here.  The first is 
that the Retrieve URL gear is not exactly robust.  Improved
functionality and error handling are on the todo list.  I'd 
envisage that in the case you encountered, a pop-up alert
would be displayed and the machine would stop.

The second problem is as you've seen STDERR isn't visible to 
the user.  I plan to allow the framework to capture STDERR and 
display it in a separate window - similar to the Javascript
console in Firefox.  The user will be able to choose to have 
that window pop up when necessary or stay hidden unless 
specifically turned on.

In the case of a machine that uses an external command, you 
can always append 2>&1 to the command if you do want the error 
messages mixed in with the data.

Yes eventually, but there are a number of higher priorities on
the list.

Thanks for you feedback.
