We have a solution that fits both use cases by default: it's the same solution we used with 1.1.0 and are now using with 1.2 beta1, which is setting DeferUpdate to 1 ms. You and Pierre have not provided any test cases which demonstrate that 10 ms is beneficial, and Pierre admitted that the choice of that value was more of a gut instinct, which is why we changed it back until further information can be gathered. Pierre and I have reached at least a temporary agreement regarding this, so I'm not sure what you hope to gain by continuing to argue the point. ------------------------------------------------------------------------------ Ridiculously easy VDI.
