Array glitch

[Terry Dennis]

-- Run the following script in a new stack
-- At the breakpoint, the array has one entry in it
-- Go to the "Variables" tab and click the down-arrow for tSimpleArray to view the contents
-- The IDE exits immediately, with no error message
-- How do I find out what caused this?  Is there a limitation on the size of a numeric key?
-- LiveCode 6.1  Build 2005

on testSimpleArray
   put 0 into tSimpleArray[the seconds]
