Can not navigate on application software menus

[dle...@gmail.com]

Hello, I need some help.

When I try to navigate throw the different menus like System and ComPORT, the application stop working. After I need to press ESC to work again. 

Do I need to install any library to put the application work properly?

I'm working with avrubd configuration file to configurated the COM port. But when I'm trying upload the hex file the message of error appears:
