So, the tasking problem is caused by Solaris 9. I'm sure ACT or someone 
is working on this issue? Does anyone know of any progress?

Too bad I don't have the Solaris 8 CDs. It came pre-installed with 
Solaris 9 CDs bundled in SB150. :( I guess I will have to wait till a 
gnat workaround has been released. :(

How about Solaris 10? I read there is a major work out on Solaris 10 
architecture. Any news?
