@Charles:I think the bug fixes in WPF are going to make pretty much everything that uses the technology much faster. Just wish there was a way to update pre .NET 4.5 versions and that the bug fixes had been made in the .NET 3.5 SP1 stage - they really should have identified, prioritised and fixed the issues then. 

At least .NET 4 apps should benefit from the fixes, because as I understand it, .NET 4.5 is an in-place update for .NET 4.
