If construction bug in 5.5.2 ?

[Robert Presender]

Create a text entry field with content 00.00
Field script is:

on openField
answer information "Want to enter a new value?" with "No" or "Yes" titled "New Amount"
  if it = "No" then select empty
  if it = "Yes" then select text of me
end openField

Using 5.5.2, No works fine but Yes keeps repeating "Want to enter a new value?
Using 5.5.1, No and Yes work as expected.

If a bug, would someone file a bug report. I'm just a hobbyist.
