Version: (using KDE 4.4.0) OS: Linux Installed from: Fedora RPMs Open Kontact > go to Calendar > Select Month view. In the Month view, select any date and create an event. (my case was 8 hours 7am-4pm) Now right click and select copy. Select your new date, right and paste. The pasted event is now assigned to whichever date is select on Left-hand side Month/day selection box. If you want the pasted event to be pasted to the day you selected in the large Month view you must first select the date in the left-hand side calendar. Thanks
Fixed, will be in 4.4.2
Using KDE 4.4.2 and I can confirm that the copy & paste function in Kontact now works as expected. Thanks!
