I can't find the original thread referenced here, but I have had
experiences, Joseph, where the text in a field on a form is overwritten
regardless of whether or not I've hit the [Insert] key to that is
inserts or overwrites.
I think this usually happens when one has an Input Mask. I'm not sure
why, but every time I have an Input Mask, it overwrites the text in the
field, and hitting the [Delete] key to delete extra characters does no
go - I have to go to the end of the text and backspace.
