Application hangs when using Nested property sheets

[anandkrish]

I created a Main Property Sheet with 3 property pages(3 tabs). And in one of the property pages's OnCreate I created another propery sheet with 3 more property pages. When I click on the main property page tabs, It works fine. When i click the child property page tabs and then click on any one of the main property pages tabs the application hangs.

Any help would really be appreciated.
Thanks
