No vertical scroll bar visible when adding changeset to Crucible review under IE 7.0

I'm using FishEye / Crucible 2.4.1 and Internet Explorer 7.

When I try to add a changeset to a Crucible review, no vertical scroll is displayed.

This issue does not occur in FireFox.

I also tried with FishEye / Crucible 2.5.0 and Internet Explorer 7, and the problem is the same.

Attaching the screen shot for reference.
