This is the oddest thing.
Computer is Windows XP Professional
Office is MS Office 2003
User is doing everything correctly as far as I can see, but occasionally instead of copying and pasting the lines selected, the entire printscreen is pasted. It is as though he hits the print screen key. This happens using Control C, control X, or using the mouse and selecting Copy, Paste.
As a side note, but it started about the same time, when logging into his time clock software,(via IE7) the system no longer rememers his username and domain as it used to.
