Sorry if any of this has come up before, I’m new to the forum.

1. I want to create a button symbol with a photo in it which switches on the mouse rollover. I thought this would be simple enough to achieve by masking. So i put the photo into a circular mask and flash displays the instance of the button how it should look on the stage, when i turn on basic buttons, it also looks and works fine. The problem is when i test or export the .swf file. The masking ceases to work leaving the photo stuck behind the mask layer which has now become visible. I thought i had masking sorted until this happened. Any help would be appreciated.

2. Could anyone direct me to a tutorial on how to get a rollover effect on a button or movieclip so that the instance will play an animation on rollover but then begin playing backwards frame by frame on roll-off. An example would be the buttons on [www.fosters.co.uk](http://www.fosters.co.uk)

thanks a lot guys
