Yesterday, I added the Last Used On column in the Control Panel/Uninstall Programs window by right clicking a column header choosing More... and then checking Last Used On. The column is there, but is completely empty. All have been used at least once. I have run several since adding the column, thinking that the Last Used On may not be collected until activated. There are still no entries for any program. Oddly, if I sort on the column by left clicking the column header, the listing order changes from the default alphabetical. Clicking the column a second time changes the sort arrow on the header and again changes the order of the program listing. Does anyone have any ideas or have I finally lost my mind??
