Root Cause

The problem is caused by an incompatibility of the configured Java Look&Feel with the graphics card driver. It can be sovled by using another Look&Feel.


  1. Edit the file in your home directory.
  2. Remove the line that starts with LookAndFeel=.
  3. Save the file and restart MIB Designer.
