Title Body

Exception Type: ExternalException Message: Requested Clipboard operation did not succeed. Method: ThrowIfFailed Source: System.Windows.Forms Stack Trace: at System.Windows.Forms.Clipboard.ThrowIfFailed(Int32 hr) at System.Windows.Forms.Clipboard.SetDataObject(Object data, Boolean copy, Int32 retryTimes, Int32 retryDelay) at System.Windows.Forms.Clipboard.SetText(String text, TextDataFormat format) at System.Windows.Forms.Clipboard.SetText(String text) at Deerfield.Base.Controls.DataGridView.ProcessCmdKey(Message& msg, Keys keyData) in C:\Users\Developer\Desktop\deerfield\src\core\Deerfield\Deerfield.Base\Controls\DataGridView.cs:line 555 at System.Windows.Forms.Control.ProcessCmdKey(Message& msg, Keys keyData) at System.Windows.Forms.Control.ProcessCmdKey(Message& msg, Keys keyData) at System.Windows.Forms.TextBoxBase.ProcessCmdKey(Message& msg, Keys keyData) at System.Windows.Forms.Control.PreProcessMessage(Message& msg) at System.Windows.Forms.Control.PreProcessControlMessageInternal(Control target, Message& msg) at System.Windows.Forms.Application.ThreadContext.PreTranslateMessage(MSG& msg) I googled this, but I cannot get a decent answer as to why this is happening. The MSDN documentation says that this often happens when the user switches to another application, but it does not appear that this was the case.
