Dialog box in Word appears different on two identical PCs

[Craig Norton]

I have two identical PCs, however the dialog boxes that appear when running a mail merge look different. The Windows and Word versions are the same so not sure why that look different. One looks like a traditional dialog box, while the other looks like a web page message. I have compared settings within Word and both look identical.
