Scrolling Problem in Skinned Window

[ken82m]

Here's an example of my scrolling problem. Everything working fine except for dragging the scroll bar to a new scroll position.

It works fine in the listview though which of course has it's own built in scrolling.

If anyone knows how to fix this, or just disable the ability to drag it I'd appreciate it.

Thanks,

Kenny
