I have 2 Apple MacBook Pro laptops
Both running Windows natively via Bootcamp, (No VM's involved)
One is a Macbook Pro 2008 model, running Windows 7, Visual Studio 2010
The other a new Macbook Pro early 2013, running Windows 8, Visual Studio 2010
Both systems exhibit the same problem.
When running Visual Studio, and the power changes from Mains supply to Battery, VS will close without any notice, not even prompting to save, and loosing work.
Note there are no extensions/add-ins loaded. The 2013 laptop is a clean install.
No other applications close, only Visual studio.
This is very serious as it involves loss of data.
