When I display the Report "Portfolio Value and Cost Basis" (or any other report) I have always been able to hover the mouse at the top of (or in) any bar and it would show me the monetary value where the mouse is. I have been using the feature for many years. Starting 3-4 updates ago, this stopped working. It now shows the pop-up on my second monitor, and leaves an artifact on the second monitor when I move the mouse off the bar in the graph.
