Error - PlaybackFailureException was not changed by user code. an exception of type 'Microsoft.VisualStudio.TestTools.UITest.Extension.PlaybackFailureException' occurred in Microsoft.VisualStudio.TestTools.UITesting.dll but was not handled in user code

Details:

• Tool - VS 2013
• IE - IE10
• The same code works fine in VS2010, but while running on VS 2013 it does.
• Powered by VDI
• Works fine, but most often doesn't. Works great in 2010.
• Sends keys as "ttteeesst". the pattern continues to change, but the output is a malfunction.

Workaround:

• Checked both true and false for Playback.PlaybackSettings.SendKeysAsScanCode
• Checked sendkeysdelay = 1000;
