Recently and inexplicably any new workbooks that I open default to manual calculation. I read a few message boards and they said that the solution is to put a workbook in the XLSTART folder that s set to automatic calculation. This works, however any time I open an existing workbook it opens this one too. I then have to close that one out, which is a minor inconvenience but annoying nonetheless. Is there a way to have Excel default to automatic calculation without going this route? Alternatively, is there a way to make the workbook in XLSTART not open when I open an existing file?
