Assume I have a cell M24 with a formula like

=M10 + $H24 - $I24*0.35

As you can see B10 is a fix reference (due to omitted $) which should NOT be auto-adjusted but be kept.

Now I want to copy the formular to lots of cells below cell M24. therefore I mark cell M24 and click copy in context menu.

Then I drag/expand the blinking cell border to lets say the 20 cells below.
As I result I expect e.g. in cell M25 a formula like

=M10 + $H25 - $I25*0.35

Unfortunately I got

=M11 + $H25 - $I25*0.35

So the fix reference is adjusted as well.

How can I tell Excel 2007 to NOT auto-adjust fix references in formulas?
