Version: 3.5 (using KDE KDE 3.5.1) Installed from: Ubuntu Packages OS: Linux Steps to reproduce: while in the month view in Kontact, delete an event on a date that has more than one event (method I used if it matters: select event with single click, press delete button on keyboard and confirm dialog with space bar). Then select another event on the same date with a single click. The details box will continue to say "No Item Selected", and the delete key cannot be used to delete the event. Workaround: Click on another date (either an event or white-space), then click on the event again and it is selected.
This is now working in Kubuntu's 3.5.3 packages.
