Release numbers?
John,
On the 4000 and the GVP '040 card make sure that the caches are turned
off before loading your code. If it makes a difference then you probably
have some self modifing code somewhere. (overlays can cause the same sorts
of problems)
Are you actually running 2.01 or 2.1? If 2.01 you really should upgrade
to 2.04 at least.
