Hi everyone. I had talked with Apple a couple weeks ago. The iCal advisor sent the problem to the engineers to find out what is expected from these drags and drops. So I called again today. Another iCal advisor checked the notes and saw no response from the engineers.
So, I detailed the motions again. I have a Macbook Pro, started with Snow Leopard and updated to Lion. I explained to the advisor that to create a reminder, I can grab the Mail header, drag it to iCal, and drop it in the middle events column with a particular calendar selected. I told him that none of you on the forum have been able to do this; the event doesn't show up.
In my case, to make a reminder, I grab the event and drag it to the reminders column. However, the reminder doesn't appear until I either (1) close and re-open iCal, or (2) make a new reminder and delete it.
So the new advisor put me on hold while he tried it. He tried this in Snow Leopard and it worked as it did for me, including dropping the reminder. Then he tried this in a "clean" Lion (no previous OS underneath). It didn't work at all. He couldn't even drop an event.
So what to do? He said that Mountain Lion is revising reminders completely and I should look forward to its release this summer.
Bummer bummer bummer. You all were right, the event drop doesn't work, and I thank you all for not slapping me silly. He didn't know why it works on mine.
So, so sorry. Yours bummed out,
DeAnne
