Try switching off compatibility checking: sometimes this is very slow.

When I save certain workbooks (in compatibility mode) the save function
runs
for 20 minutes at full CPU utilization. When it finally completes, the
usual
buttons at top right of the window are gone. Also the open and exit
functions are diabled. Exit can only be achieve by killing the task
through
task manager. At other times the problem does not occur.
Makes it very hard to upgrade from Excel 2002.
