We believe we've located the problem, which seems to happen in systems with Windows 8 and no VS2010 installed. ViEmu 3.0.9 will be released shortly and hopefully will fix this.

var address = new EOD.OrderDetail
{
Address1 = "1234 Some Road",
Address2 = "Suite 300",
City = "Somewhere",
State = "ZZ",
ZIP= "12345",
Country = "US",
Company = "Acme Widgets",
Attention = "John Doe"
};

The results are different depending on the location in the same string.  As an example, changing the City string with the cursor on the 'm', you get this when ci" is typed:

var address = new EOD.OrderDetail
{
Address1 = "1234 Some Road",
Address2 = "Suite 300",
City = "",
"
State = "ZZ",
ZIP= "12345",
Country = "US",
Company = "Acme Widgets",
Attention = "John Doe"
};
Cursor lands before the " on the new line

When the cursor is on the 'r', you get this:
var address = new EOD.OrderDetail
{
Address1 = "1234 Some Road",
Address2 = "Suite 300",
City = "",
Stat"e = "ZZ",
ZIP= "12345",
Country = "US",
Company = "Acme Widgets",
Attention = "John Doe"
};

Cursor lands after the t" in State

Turning off the auto-insert pair corrects the problem.  Not sure if this setting will be compatible with ViEmu or not...

ci"

(read change in quote) to change the entire contents of the quoted string.  This used to work fine (3.0.4 VS2010 Win7).  Now it produces a strange effect.  Take as an example:

                Console.WriteLine("Press Enter to end program");
                Console.ReadLine();
                return;

I place the cursor in the "Press Enter to end program" string and type ci"
rather than ending up with the expected:

                Console.WriteLine("");
                Console.ReadLine();
                return;

I end up with this:

                Console.WriteLine("");
       "         Console.ReadLine();
                return;

With the cursor just before the " on the Console.ReadLine() line.  Smells like a bug.  Change in word ciw still works

Here's the config:
Windows 8 x64
VS2012 Ultimate (in case it matters)
ViEMU 3.0.6
Resharper 7.0.1098.2760
