So (foolishly) I let the software updater delete Java 6 (which only Apple provides), and I installed Java 7 from java.com. Was running ASDM 6.4.9, all I got was the Java 7 splash box. Updated ASDM to 6.4.9-103, same problem.
I can run ASDM in one of my VM's, but it's a pain. Any ideas on fixing this?
Thanks,
Richard
