Loader Component in "Forms Application"

I have observed a very strange issue when using the Loader component within a form-based application in Flash MX 2004 Pro.

The movieclip (.swf) loaded is distorted as if it had been scaled, although scaling is set to “false” and the size is correct.

If I copy the exact same Loader component (loading the same movieclip) into a traditional timeline-based Flash document the movieclip loads perfectly without any distortion.

Does anyone have any idea how I can make this work in my application?

Any help is GREATLY appreciated!
