Ok - related problem to the one immediately above (because I'm still unable to get a right-click menu, for a calendar day on the right hand side of the screen)...
How do I delete a 28/12/08 session in Plan, under the following circumstances (as an eg.) :
It's on RHS of screen, so no right-click > delete
Double-clicking lets me edit it, but then the only options are Save and Back (not Delete)
Can't delete using Plan > List because only 40 items display on a page, and only one page (and there are more than 40 items older and newer than it, so resorting doesn't help)
Can't find a date with "Search" in Plan > List (and don't know whether I should be able to)
I could delete other entries (that I still want) until the 28/12/08 session appears on the List page, but that doesn't seem a great solution. Is there another one? Thanks
