Netbackup console screen turns white.

Hello,

I am using Netbackup Enterprise Server 6.5 on a Solaris 10 workstation.  When I try to do a restore the console turns white and shows a watch for the cursor after about a half an hour. I increased the INITIAL_MEMORY to 256M and the MAX_MEMORY to 1024M in the nbj.conf file, rebooted the suystem and tried another restore and got the same results.  The screen turns white and never recovers. Any ideas on how to fix this?

Thanks.
