System.OverflowException:Arithmetic operation resulted in an

Running OE 11.5.0 with Win7 Ultimate 64-bit.  DevExpress WinForms Control Library v14.1.

I created a new form (Form1.cls) and dragged a DevExpress RichEdit control onto the form.  An error window immediately appears with the following text: "System.OverflowException: Arithmetic operation resulted in an overflow."

Can anyone assist me with resolving this issue?

The Stack Trace output is:
