Version: 3.5.6 (enterprise 0.20071012.724442) (using KDE 3.5.8-7.fc7 Fedora, Fedora release 7 (Moonshine)) Compiler: Target: i386-redhat-linux OS: Linux (i686) release 2.6.23.1-21.fc7 Make a correction to an existing calendar Event or To-do. Press 'Apply' and 'OK' to save the changes. The Event or To-do does not display the change. In the case of a calendar Event, change the view, e.g., from 'month' to 'day' and back again; the Event correction is now correctly displayed. In the case of a To-do, change to, e.g., one of the calendar views or to the 'List' view, and then back to the To-do List; the To-do change is now correctly displayed. Alternatively, one can Quit and then restart KOrganizer, and the changes will now be displayed.
I can not reproduce this on trunk r865573.
closing then. please re-open if this problem continues to happen in KDE 4.1 or higher.
