Are you selecting the entire rows or just a range of cells?
When you did the SHIFT Edit>Copy Picture which option(s) did you choose?
I tested a 10 column by 60 row matrix and had no problems with either "as shown
on screen" or "as shown when printed".
I don't think you can select the entire sheet.
If I try all I get is an error message that "too big, will be truncated"
