Unable to Record actions in a modal popup

Hi,
           I am testing a web application and there comes a point, where i have to click a icon, which navigates me to a popup, at this point, i have 2 popups open, 1 which is a regular HTML popup with blank content (plain white screen is displayed), and another popup which is a modal popup.

Telerik connects itself with the initial home browser and records all actions on it, upon navigation it also connects to the new HTML popup (the teleric toolbar is displayed on top) , but with regards to the modal popup, Telerik is unable to connect to and no action on this modal popup is recorded.

Any advice on this would be much appreciated.

Thanks!

I am attaching screen shots of the screens with brief descriptions mentioned below

Screen Shot 1:

User Credentials are input here and navigates to the home screen. This screen is recognized by Telerik

Screen Shot 2:
This screen is recognized by Telerik as well. Once in this home screen, I click the “Central HR”  button (bordered in green below)  and this navigates me to a new window

Screen Shot 3:
The click on the previous screen opens 2 popups (new windows), one is a basic HTML new window (blank with no data) shown below on the left and a Modal popup (with all further functionalities) shown  below on the right. This modal popup is not recognized by telerik and  does not record any action on this modal popup. A majority of our testing has to be performed on this modal popup
