What is wrong with this Script logic?

[Peter M. Brigham]

I tried this:

on closefield
   put "closefield" && the seconds & cr after message
   hCheckEntry me
end closefield

on exitfield
   put "exitfield" && the seconds & cr after message
end exitfield

on enterinfield
   select empty
end enterinfield

on hCheckEntry pData
   if pData is an integer then exit hCheckEntry
   answer "Please enter only whole numbers!" as sheet
   if the result = "cancel" then exit to top
   select text of me
end hCheckEntry

It looks as if "select text of me" sets the field up to throw a closefield message even if the text of the field is not changed. It should throw an exitfield message. I've never seen this before. It is anomalous, to say the least. 2008 MacBook, OSX 10.7.4 (Lion), Rev Studio 4.5.3, build 1210.

Only the ask dialog should be modal and stop the loop until you dismiss it, then evaluate the entry and loop again or exit. That's not happening. It looks like the script keeps running even with the dialog up, the loop backs up with multiple calls to the ask dialog, and everything hangs.
