Hi Mark,
Minor bug report : Pie Chart graph left open (a parent portfolio selected with several subportfolios in it), then go to the Portfolio Editor and create a transaction in an investment in a subportfolio of the parent. After the creation, the pie chart is not refreshed (should be automatically, yes?). And same after menu Windows > Repaint Graphs, the Pie Charts is still not refreshed, the new allocation not displayed. I have to select another portfolio for the Pie Chart then come back to the original portfolio in order to see the new allocation.
PS : display by sector.
