Resend - Unitialised EDITSTATE

[jeffl]

People, when trying to run DebugApiSpy.exe in encounter a divide by
zero. It seems there is a circumstance where the EDITSTATE block can be
unitialised.  I have not found this yet and I am not sure how to track
it down.  This patch fixes the instance where the problem occurs for me.
    There are other instances where a divide by zero could occur.
