Created attachment 69022 [details] agenda layout of egroupware, a good example for layout Version: 4.8.x (using KDE 4.8.0) OS: Linux When you use many different Calendar sources (ie more than one), and one slot is already occupied by an other users incidence, then you cannot select any time "behind" that incidence to create a new one at the same time. Reproducible: Always Steps to Reproduce: Have >2 calendars with a slot say 8-12 occupied by an incidence. Try to create a new incidence from 9-10. Actual Results: You cannot select a time from 9-10 with the mouse or keyboard since the slot is already taken. Expected Results: Have each incidence to cover only 90% of the width of a day so you can still select a time "behind" the already displayed incidence, a concept that several other groupware suites are using. Arrange all incidences in a way that there is always some of the "grid" visible behind incidences so you can select a time to create a new incidence. Screenshot of eGroupware layout as example attached.
Created attachment 69023 [details] Agenda layout of KOrganizer as a comparison, not so good layout
Moved on to KOrganizer 4.9, no change, still not able to create a new instance in an already taken slot, only create on another day or at another time and then drag it to the right time, however that confuses attendees since they will get two invitations and a cancelation. So only viable workaround is to manually create an instance via "New...".

Bug 443335 suggests using a modifier key on the click.
Perhaps this could be related, but the Marcus Bains line prevents clicking the events/tasks behind it. It should be made transparent to clicks too.
