Autorecover takes so long
 

Why does autorecover takes such in inordinate length of time in Excel 2007 to
save in comparison with just saving the file? On my quad core machine with a
Windows 7 installation about 2 weeks old, my 7 meg file varies between about
15 and 30 seconds to save . Autorecover however holds up the machine (paled
olut "not responding") for anything up to 10 minutes. I've had to disable it.
