Okay, we understand you did it on purpose and you prefer it that way, now change
it to the way most people expect it should work! You are unwittingly positing
the idea in the mind of your customers that your program contains silly bugs. Of

What is relevant is this "feature" may cost you money unnecessarily. It is
simplist to avoid this by changing it to what people expect.
