It could be a graphics driver problem. Try moving or renaming the
following files

For IDL 8.0 and 8.1
/Applications/itt/idl/idl80/bin/bin.darwin.x86_64/gl_driver. so
/Applications/itt/idl/idl80/bin/bin.darwin.i386/gl_driver.so
For IDL 8.2
/Applications/exelis/idl802/bin/bin.darwin.x86_64/gl_driver. so
