I remove cmbPort.Items code it runs fine. .Jar runs fine! Not .exe

v 1.40 jSerial

If using jSerial put the attached jssc.dll file in the project folder and add:

#CustomBuildAction: After Packager, %WINDIR%\System32\robocopy.exe, ..\ temp\build\bin\ jssc.dll

Note that it is a Windows 64 bit dll.
