Digital signature invalidated by checkbox fields

Hi,
I have created a rather complex form using LC 8, with flowed pages and a number of text fields, and a signature field.
If the form has any checkbox marked by the user, it happens that after signing the form, the signature logo appears as a yellow triangle and the error message reports that the document has been modified after signing it (but it is not true).
Otherwise, if I set the signature field in order to block all fields after signing, after signing the form the signaure appears as invalid, and the error message reports that the documents has been modified or damaged by the signature itself!

Can anyone explain how to solve the issue?

Thanks

okay, just kidding.

My only guess is a bug.

Could have to do with a script triggered by the checkbox. Check the scripts on the form. If the script modifies the form based on the checkbox value, that modification may invalidate the signature. Scripts that change the form at open time and signatures usually don't mix well.
