Drop down value lists in IWP

Hi Group -

I'm using FMP9Adv in a WindowsXPPro environment, various browsers. I
have just noticed for the first time (I don't do much Instant Web
Publishing) that when I specify a field as a drop down list, IWP seems
to limit entry in that field to the value list, even though I don't
specify that validation, and even if I choose the option to include the
"other" choice in the field format.

Have others noticed this issue? Any suggestions for a workaround to
keep my clients from whining? They want a drop down, but then they want
to ignore it.

Many thanks in advance -
James
