On my iMac I cannot enter an all day event in iCal. All day events entered via my iPhone or Mobile Me also do not show up on the iMac. Just upgraded to Lion, no problem before this!
Open iCal and from the View menu check that Show All-Day Events is checked.
Many thanks. So simple and obvious I didn't even think to look there.
Thanks for these posts. Yes, simple when you know how ... but this has been driving me crazy!
