4.0, Can't print ERD's from data modeler.

I created an ERD in the data modeler in 4.0 and tried to print directly to the printer.  I saw in the windows print que a flash that the printer received a request but didn't print.  I saved and closed 4.0 and brought up in  sqldeveloper 3.1 and was able to print fine.  I am running on windows 7.  I suspect a bug.

Thanks,

Ken
