Scrolling and buttons problem

I’ve been working on the project for quite some time and stumbled into the problem. I use XML feed to create products catalogue divided into several categories. I read separate XML for every category and dinamically duplicate movie clip as many times as there is products in the category. I have a scrollbar and it is working fine by dragging the scrollface and by pushing buttons to scroll. I also made it to work by mouse wheel. Client also want it to work by dragging the main content, and this is where the poblem emerges. As soon as i add

contentMain.onPress = function()

the buttons in the main content stop working. Is there a way to overcome this?

If you need the code, I’ll post it. Thanx!
