I am copying a portion of a large spreadsheet, a portion 5 columns wide, and
3 rows tall. Other than the last column, all is well. The last column has a
lot of data in it, between 10-20 lines of text, separated by an
[ALT]+[ENTER]. I find that in pasting, I'll usially get between 13-15 lines,
but it will abruptly cut off, mid-word. Even copying just the cell itself,
and closing other programs produces the same results.

Any suggestions?
