Problem with Flash form in external SWF

Hi everyone,

hope somebody can help me or point me in the right direction with a problem that i am having.

i have a main flash movie loading an external .swf that contains a scrollPane/lots of UI Form elements.

The external swf plays fine on its own, but causes problems when loaded into the main movie. i am not able to select any fields and labels disappear.

Any idea what is going on?

thanks in advance,

Seb
