:>An SRB routine running in PSW key 8?!? WTF?

Nothing at all wrong with that. It knows that the areas that it needs to
modify are in key8.

It is a quite bad practice to run in key0 when it is not needed. All sorts of
bad overlays can happen.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
