DemoNET40 Crashed in windows 7 with .net framework 4.0

[valinoment]

When I run the Release 1.5.0 NET40 demo then click 'X' close button, it will crash with unhandled exception. ( I found earlier release version occured the same crash issue like 1.4.0, 1.4.1 etc.)
I caputed the event log as blow.

Application: MetroDemo.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileLoadException
