Cannot 'save as draft' in Mail 5.1
Hi, I've a problem with saving draft emails since I upgraded to Lion.
Example: My wife spent a couple hours replying to a long email from overseas relatives, most of the time spent exporting/resizing large .jpeg photos from iPhoto so the attachments did not mean a huge email.
She was interrupted but not too fussed because previously the emails would be saved as drafts if she closed a message before sending it.
But not this one.
My mail 5.1 help instructs to press the Save As Draft icon. There's no such icon on the toolbar nor is there one selectable from the Customise Toolbar option. File | Save As... is greyed out.
Mac is a mid-2010 iMac 27" quad core. Mail account is a MobileMe account that I am hanging on to until I upgrade my iPhone from a 3G (that cannot support iOS5 or Cloud).
Any help with settings or troubleshooting would be appreciated.
