The "repeat with" structure in hc 2.0 apprently prevents
the programmer from modifying the value of the counter
from within the loop. Try the following script:

on mouseUp
  repeat with i = 1 to 5
    put "top of loop: i = " & i
    wait 2 seconds
    if i > 1 then put i - 1 into i
    put "bottom of loop: i = " & i
    wait 2 seconds
  end repeat
end mouseUp

This "feature" is undocumented as far as I can tell.
C programmers would call it a misfeature. At the very 
least, the hypertalk interpreter should complain about 
attempts to set read-only variables.

(Just another unix guy too lazy to program the
Mac in a real language. And paying the price).
