unloadAndStop() problem

I’ve run into a problem with unloadAndStop().

Brief description of project:
A parent swf has a stage event keyboard listener.
The parent loads and unloads the child swfs.

If there is a child swf with a radio button or a checkbox components, the keyboard event listener is killed in the parent when it unloads the swf and loads the next child. And in the debug window I see an ioError:

[FONT=Times New Roman]Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.[/FONT]

The error never occurs if the child swf has a text input component or no components. In all cases I am removing the eventListeners from the child swf before loading another child. Does not matter if unloadAndStop(false) is used either.

The problem does not occur if I just use unload();

Anyone else seen something like this?
