Interface not shown when designing the application.

Interface not shown when designing the application.

  
Hi !

This is some-kind of a weird problem where-in I am not able to see my user interface, when I press the 'Interface' tab when designing the application.

When I press the 'Interface' tab and click on any of the 'WebScreen' no elemnets are visible, except the black screen. I tried to check out the properties, but was not able to figure out the problem.

Any hints ?

Thanks.
