Until I got my workstation, that was me every time I hit "Refresh" on my pivot tables.  

@Tristerin lmao tru, even with just a thousand or so numbers my mid-2012 MBP took a sec to refresh when I was messing around with pivots last night. 

For this it's more I compulsively save the workbook every 5 seconds or so, I have it mapped to a press of my middle mouse button and I tend to spam that. I feel sorry for anyone else with their dropbox notifications on though, since it notifies everyone else with access to these files any time I save

lolol I do the opposite, not save enough, get crash, rage like demon fire, rinse repeat
