I'm not exactly sure why this is happening with the next and previous buttons in an interface because the problem isn't consistent. Using Actionscript 2.0 and publishing to Flash 7. When I first run the interface, the next and previous buttons work fine. But sometimes when the onRelease occurs, the button doesn't go to its rollOver state. Instead it looks like its default rollOut state. But if I move the cursor just a pixel, it'll go back to its rollOver state, even though the cursor hasn't wandered outside the boundaries of the movieclip. I think I had the same problem a while ago and I remember fixing it... but for the life of me I can't remember. Anyone else ever come across this?
