I just upgraded to v2.62.2+170203 (the latest build), and everything seems to be okay, except for the horizontal scrolling on the "Display Responses" page. When I try to either single-step (by clicking on the right/left button) or page-left/right (by clicking on the empty spaces at either side of the scroll handle), the data in the list sort of jerks around a little bit, but doesn't actually scroll. Holding down and dragging the scroll handle works fine, however.
This only seems to happen on "Display Responses". I have tried scrolling other lists, such as "Display Participants", and there, both single-stepping and page-right/left work okay.
Hope someone can check this out and see if the problem exists on other installations of this same build.
