I think I'm correct in saying that the default TIB_Query setting of
RefreshOnParamChange = true, causes the RefreshAction setting to be
ignored. Could this be changed? (V4.2.Fp)

Given that there is a certain amount of extra code (BeginUpdate(),
EndUpdate())to be written when using RefreshOnParamChange and you
only want one refresh to occur (when changing multiple params, this
would be the norm, I'd imagine), it seems simpler to have
RefreshOnParamChange default to false, use a TIB_Query->Refresh()
call when needed, and keep the benefit of the RefreshAction setting.
Or have I missed something again?

Cheers,
Steve
