Assuming a "slidebar" is a scroll bar I don't see any change in behavior
between Excel 2003 and 2007. When a scroll bar from either the Forms or
Control Toolbar toolbars is used (you didn't say which you were using) and a
linked cell changes value, the sheet_change event is not fired. I assume
you're using the sheet change event. But the scroll bar change event is
fired for a Control Toolbox scroll bar. And a macro attached to a Forms
toolbar scroll bar would also fire and it could calc the sheet.
