Hello- I am not personally having the problem, and I've not seen this before. My Aunt and Uncle have a 24" iMac bought in September 07. I installed Leopard for them this weekend. They emailed me today told me that they where getting an "Undelete" button in mail now, which they had not had in Tiger. I haven't ever seen an Undelete button in my own use of Mail either (I currently use Leopard as well) So I was looking at the settings for mail on their machine via Remote Desktop. I seemed to be able to fix the Delete button switching to Undelete problem, however if you press the delete button on a message now, the message disappears from their inbox, but doesn't go to the Trash in Mail... The trash folder remains empty, then if you click back on the inbox after going to look at trash, the message is back in the inbox!? WTF?? Can anyone shed any light on this? Thanks.
