Hello,
Sorry about the delay in response but I was trying to find the patch
number before I posted the replies. Many thanks to Ade Faleti, Skye Poier, and
Frank Cusack. Apparently this is a known bug in 2.6. My Sun rep has not giving
any patch info yet, so if anyone knows a patch ID I would appreciate it. Thanks
guys.
Rob.
