Scrollbar missing on Presentation element of workflow

I've exported a workflow from one of our VCO build 4.1.1_733 servers to a new build 5.1.1_2942 server. This particular workflow modifies values stored within a configuration element. When you execute the workflow running on the 4.1.1 server, it displays a scroll bar on the right hand side of the presentation window-it's missing on the 5.1.1 server, so you can't access some of the values. Anyone know what might be missing? I don't see a property within the WF to define anything for this. Thanks.
