I guess I can agree with that, however, it is not fair to assume that not enough
testing was done in multi-variation mode when it is one of the listed selling
points of the program. I do not think we have it out for Steen with this -
simply an acknowledgement that a bug exists, and it will be looked into. I find
it no mystery that bugs can exist. Helps us all to point them out, right? At
least this one is easily reproducible.

I can now verify that this odd behavior not only happens under any Chessbase
interface, but also when using Gandalf 6.0 in MV mode under Arena 1.092. Once
again, mate is instantaneously found in SV mode.
