I'm trying to work with an 80 meg spreadsheet with tons of calculations and
macros. Whenever I change a column, it take 45 minutes to 1 hour on a dell
610 (pentium m 1600). If I run the application on a dual processor machine
or a dual core, processor, will Excel take advantage of the second processor
or core?
