Could not EngineMaster make one dummy call to DlgPrefCrossfader
upon init to head this off? This would preclude any need
for special one-time code or funny entrance points. It might
mean that DlgPrefCrossfader has to check for silly conditions
(unitialized data, etc) but those sorts of checks are not a
bad idea in any case.

Is this the QString("literal string") language conversion stuff,
instead of "literal string"?

I'm willing to look at this sort of crap. I take perverse
pleasure in large amounts of repetitive tasks because I can
make a machine do it instead.
