Even the default gridlines remain visible within the selected block, so there is absolutely no way, short of memorizing them, to tell afterwards which cells have been selected. Since the upgrade, when I select a cell or group of cells in an Excel spreadsheet with the default white background, the cells are not highlighted at all and are indistinguishable from the surrounding cells.
