Excel is messing with the math coprocessor

I have just noticed that Excel is changing the floating
point round off handling in the math coprocessor for my
C++ and Fortran DLL. Has anyone run into this ? I am
getting ready to try venturing into _Control87 calls
when my DLL is called from Excel.

I have verified this problem in both Excel 2003 and 2010.

Thanks,
Lynn
