I downloaded and installed Sencha cmd 5 and started working through the getting started guide. Note that I am a complete newbie with Ext-js.
I leave my command window open at the "Waiting for changes..." and I go out to lunch (Or just do different work). If I leave it like that for an hour or so I will get an error message stating

I am using Windows 7 64-bit on a Dell Laptop with an Intel Core I7 Quad core processor and 8GB of RAM if that helps.
