Are "bus errors" just a way of life or has something been corrected?  I have looked through older forums and it seems that I have tried all the suggestions but still get them on a daily basis.  I have noticed however that I get the error when I am running MC with Adrenaline, but usually only first thing and then it's like the Adrenaline "warms up" and then the errors go away. I don't get them so much when running MC Soft.  Unfortunately I am at the end of MC updates for Tiger. 

A lot of work has been done to correct Bus errors in the software Steve. What version are you running? IS it still 3.1.3 as is in your profile? If so, you may want to see if you con upgrade as the situation has improved.

Yes I am at 3.1.3 still.  There hasn't been any other upgrades for Tiger, has there?  How many issues would I Run into if I were to upgrade to Leopard on this machine? Is it even feasible?

You would need to go up to 3.5.9 if you want Leopard.
