Cannot run in step "Handle 'Alert' dialog"

[Totti]

After record my steps in scenario, I run again recorded steps, and then I face in step: "Handle 'Alert' dialog"  (I need Click [OK] button from Alert message box) with error message , and cannot execute next steps.
Error message:

Failure Information:

How to fix this one ?

Hello Totti,

The "OK" button of an Alert dialog should be automatically clicked. Do you think the default timeout of 5 seconds is sufficient for your scenario? If not you can just change the HandleTimeout step property to a bigger value.

If that doesn't help can you please elaborate more on how the application behaves? For example you type some text in the main application window then click a button which pops up an Alert dialog, is that the case or is it more complicated?

Kind regards,
