(I am Margaret's consultant)
I spoke with Margaret and explained to her that Softrak assigns different grades (in the Release Notes) to Upgrades, and that she should check with me only for ones graded "Difficult". The PO 9.2B upgrade was graded "Difficult". Most upgrades, such as GridView 9.2B which came out yesterday, are graded "Easy".
I took a look at her data. While PO was clean, IC was not, and after rebuilding IC, the blank (white) lines disappeared.
I know she is using IC 9.2A (150428), which has known incompatibilities with PO 9.2B. But when she tries to install the latest IC 9.2A service pack, her anti-virus software is complaining that Inventory.EXE is a virus and will not let the install proceed. She is working with her IT people on that issue.
