[javascript-dev] Re: progress indicator...

Josh, thanks for the hints.
I gave this a shot, and didn't get the results I hoped for!
Here's a js that uses a task instead of a for loop to copy the file.  It just sort of stops after one iteration, even though I specify the task to run 11 times.  
Clearly it has to do with my interval of "1", so how do I get it to execute the task asynchronously without guessing at the interval?

I'm also confused about something in the JavascriptInMax documentation (pg 34):
"Although the overall timing accuracy of a Task function is high, the latency between the 
scheduled time and the actual execution time of a Task function is variable because the 
function runs in a low-priority thread."

BUT LATER on pg 45...

"In summary, a function will execute at in the high-priority thread... 
? if the function?s immediate property is set 
and 
? the js receives a message to invoke the function at high-priority 
or 
? the function is executing via a js Task object "

Aren't these 2 things contradictory?
