pop not getting timed out in vbscript file

[tester_rahul]

I am using the following code of lines in a vbscript file:

Code:

Set wshShell = WScript.CreateObject("WScript.Shell")
WshShell.Popup "Do you feel alright?", 2, "Question:"

A pop up appears as expected but the popup does not gets timed out.
The code is working fine if i use it through QTP.
Any idea what could be wrong.
