defaults write com.omnigroup.OmniFocus LongOperationIndicatorDisabled -bool YES

in Terminal will disable the long operation indicator (the spinny wheel and message about what is going on) globally. this is an ugly workaround for now; I've tracked down private API that would let me fix this, but I was *really* hoping that they'd fix this for 10.5.1. We may have to take matters into our own hands... =(
