My client has an issue dragging multiple attachments from an Outlook 2011 message to his desktop. After selecting the attachments, he must hold the mouse button down for several seconds or only one message will come. The more attachments, the longer he has to hold the mouse button—sometimes 10 seconds or more. This wasn't a problem until he migrated from his Core2Duo MacBook Pro to a new iMac (with 1TB flash storage!).

Anyone else encounter this issue? Thanks!
