Revolution is very slow to refresh fields. How can I speed it up?

The ticks to complete the operation isn't used for anything. Suppose  
I have to process the elements in an array, and there can be any  
number of elements in the array. I might do something like this:

set the endValue of scrollbar "progress" to \
   the number of lines of the keys of myArray
put ticks() + 10 into tTimer
put 0 into tProgress
repeat for each element tKey in myArray
   add 1 to tProgress
   if ticks() > tTimer then
     put ticks() + 10 into tTimer
     set the thumbPosition of scrollbar "progress" to tProgress
   end if
   -- process element tKey
end repeat

This guarantees that the scrollbar will update a maximum of six times  
per second. If there are 10,000 elements in myArray and they process  
quickly, this means that the scrollbar is being updated too often  
unless the scrollbar is 10,000 pixels wide ;-)
