What seems to work the best is overflow-x: scroll; in all three sidebar css files. This also works in Firefox.
The overflow: auto; approach did not work at all in Firefox and added a vertical scroll bar in ie7 which is not needed.
The above eliminated the vertical scroll bar and placed the horizontal scroll bar at the bottom of the page. The pages were the second page of the Submissions and the History pages of each submission.
I think there is a formating bug that needs to be addressed on this. Our standard install of OCS 2.1.2 had not been modified prior to this problem occuring.
Just thought I would let you know in case others run into the same problems.
As always thanks to the PKP team for helping us all to address our problems and issues.
Have a GREAT weekend.
