When copy a chart of numbers from the internet and paste them into excel, i
always get a long singular column of numbers instead of rows and columns of
numbers. This doesn't happen on the Windows version, but only on my iMac.

Is there a particular setting that i have (inadvertantly) set that causes
this or is this one of the differences between the Mac version and the
Windows version of Office??

Office 2004, OS X 10.5.2
