Hello Again, Sorry about the last post - I JUST figured this out (it was just by chance that I tried something just for the heck of it).
I figured, since Flex uses the decimal values "Zero through One" to specify Alpha values (versus 1% - 100%), I would try the same thing when it came to Scaling MovieClips - and it DOES apply. Either I overlooked this, or it's not in the documentation... Coming from a heavy Flash background, I am obviously going to try and drop in most of my code Verbatim, since I was already coding in AS 2.0 - With that said, I thought there would be very little tweaking involved - but I guess I will still have to sift through the docs, and find all the small changes that were made - especially things that relate to coding for Flash, and converting it to Flex.... Just thought I'd post the solution, in case this happens to anybody else.

When it comes to Flash, it is incredibly simple to manipulate assets directly on the stage - like dragging, dropping, scaling, etc. When it comes to Flex, it's a bit different. Flex seems to be very "Container-Centric", and it's not as simple to drag assets around on the stage. When it comes to dragging and dropping "Data" from one control to another, YES - Flex made that quite easy to do. But graphics are a bit different. This is where I may be a little fuzzy, and need some direction. In my Flash App, I obviously have a main stage, as well as several layers - so things appear to be on top of one another. On the sides, I have all my navigation controls, on the bottom I have all my Zooming and Panning controls, and on the top I have all my drop-down menus. It looks like a very typical Windows-type application. When the user wants to load a new map, the app fetches an external SWF File, and loads it using the MovieClipLoader control. Once it's finished, the user can pan & zoom the maps. They can Pan by simply dragging the map with the mouse cursor, and they can Zoom the map using the Slider Control (also with the Mouse Wheel, in which the Scroll event gets broadcast to the Slider). My main problem with the Flex App, is tying the Slider Control to the Zoom level of the SWF Files. Maybe I am doing something wrong, but here is how I am doing it: I have a SWFLoader which loads the Map - which works beautifully upon the initial load. Once the Map is loaded, the user can Zoom the Map by dragging the Slider Control back and forth. The Slider Control's value is bound to a Function, which in essence scales the content of the SWF Loader. Assuming that "platVectorImage" is the name of my SWFLoader, the function that gets called is the following: private function scalePlat( zoomLevel:Number ):void { platVectorImage.content.scaleX = zoomLevel; platVectorImage.content.scaleY = zoomLevel; } And here is the function that kicks off, when the "onChange" event of the Slider Control gets broadcast: private function onPlatZoomSlider_Change( event:Event ):void { var zoomLevel:Number = event.target.value; scalePlat( zoomLevel ); } When I change the Slider Control, I get erratic results - almost like 1,000 times Zoom, or something crazy like that. I would have thought, by setting the value to "100" which is the starting value of the Slider Control, that it would cause the SWF Loader to reset the SWF file back to it's original size (which is 100%). I will post the remaining code if I must, but I wanted to see if anybody could throw some suggestions my way - as I'd like to think that I have a good feel on how to write Flex Apps. I am a very accomplished Flash Programmer, and have a very good grasp of writing clean ActionScript. But at this point, I am not even sure if using the SWFLoader is the most appropriate control to be using.
