I wrote a script that opens 4 different browsers (siebel applications with different user ids) and this script works with these 4 different browsers. When running the script at the beginning, I have no problems but in the middle, I get this strange dialog box from internet explorer 8:

To display the webpage again, internet explorer needs to resend the information you have previously submitted.
If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click Retry to display the webpage again.

The reason why my script is refreshing the browsers is to gain control of the browser so that it can perform the necessary operations in that browser. To handle this problem, i have tried to use recovery scenario but is of no use. Does anybody know how to disable this popup or any workaround for this?

Thanks in advance.
