Can't add filter to button... [newb]

Hi

I’m sure this is a simple misunderstanding of how flash works.

I’ll try and explain as best as possible.

I have imported a JPG in to my library, converted it to a button, and then I animate the button in from frames 1-30. I then stop() the animation.

If I hover over the button in the preview, the cursor changes to the hand as you might expect.

Now, if I double click on the instance of the button, I get to the “edit in place” screen, with the 4 frames - Up, Over, Down Hit.

I’m unable to apply any filters to this button. It says the “button” is a “bitmap” in the properties.

How can it be both? And what is the recommended way of doing this.

It seems I can create a new instance of the button on the “up” frame and the “over” frame etc, but this seems wrong plus they all need different names so that makes no sense.

Surely I should be able to animate a button, then have it respond to hover/click etc and apply filters.

Thanks for any pointers.
