Button Resets When Masking

Hello!

I have one problem. I believe that it is easy to solve it I just can’t figure out how… :h:

So I have a button with on roll over, roll out functions and down state in my movie clip masked. When button is unmasked and pressed it shows down state. So far so good. But when mask hides this button and shows again it comes up in normal state so you can roll over and roll out again…

Well, maybe my english is not so clear but I’ve created a perfect example to show what I am talking about :slight_smile:

Any help or hints much appreciated. Thanks in advace
