I have spreadsheets going easily from 16000 to 64000 lines, I used to make
EXCEL 2003 charts by using 3-4 worksheets easily. They were big but ran very
fast. EXCEL 2007 is simply very slow, even if I try to do a chart from
scratch.

Simple line charts, scatter points nothing graphically demanding and my
computer is a P4 full of memory.

Anybody out there with the same problem?
