The Circuit Builder option in Panel Editor does not work properly. When selected, the pull down menus display with jumbled characters, as though two lines are superimposed. The application is corrupted. None of the submenus can be activated. Please see ¡°screen shot 121618¡± in Photos .

The problem occurs in an existing control panel file, and a new one also. I tried reinstalling the current JMRI v. 4.12+Rb6a9bb1, and then installing v. 4.13.6+Rcb07def, but with the same result. The JMRI InstallTest ran okay. I do not know how to verify the checksum of the installation files; perhaps the application is corrupt. The Java edition is v. 8.0.191, the latest. I also reset the computer. Is there a solution to this problem?
