Not able to recognise browser

[Supriya3072]

Hi, I am trying to script for a web application using DP. The web browser title has test environment version name along with the timestamp. When I record the actions, it records following properties of the browser: Name, title, ( both the properties have timestamp in them which refreshes everytime you navigate), openurl (which is url of the page). When I use these properties in DP, it throws error that browser cannot be found. I have used all available properties which QTP has recorded when I record the actions; I have also tried updating Base Filter properties to add 'openurl" property as base property. The same approach has worked well for other web apps in the suite. It is only this app that we are not able to automate for. Any sugeestions? Someone had suggested patch (QTPWEB_00037); which is not available on HP site anymore.
