Last night I worked on a project & I use (ctrl+s) frequently. After 3 hrs into the project, VS10 disappears off the the desk top with no warnings.
I restarted VS10 an a message asked if I wanted to save the previous work & I checked "yes". About half of my project was missing (15mins).
Don't understand why the auto save didn't at least keep up to the last 2 mins of my work.
