LSO S3 - PO20.1

Has anyone else run into this issue?  When we are looking at a line on PO20, the first detail tab works fine - provides information relevant to the selected line.  But the subsequent tabs (specifically tax, pricing, cancel) seem to grab data from the first line of the PO or the first line showing on the screen (line 6, 11, etc).  I just submitted an incident on the infor extreme site because I couldn't find this problem documented anywhere else.  However, I find it hard to believe that we are the first company to run into this.
