Pop-up Message in Form Personalization is not closed when pressed Ok Button for One time.

Hi,

I have created a form Personalization which restricts the User to Transfer item to wrong Sub Inventory. So for this Form Personalization, I have used Trigger Event as "WHEN-VALIDATE-RECORD" and Message Type as "Show".  Transaction Type is Miscellaneous Transaction

Now, when user is entering wrong Sub Inventory Name for Particular Item, The Pop Up Message is displayed but the Pop-Up is closing only when we press Ok button more than Trice. I want Pop-Up to be closed when we press OK button only for once.

Is there any one can help me in sorting this issue. Please let me know is there any set-ups required.
