Edius 4.51c YUV curves/waveform display broken

[Claire]

In Edius 4.51 adjusting YUV curves no longer updates the Vectorscope & Waveform display immediatley, one has to mouse away from the curve to some other part of Edius making this once simple procedure irksome.

I am using the NX card.

I also have this problem with the SP hardware.

This issue is resolved in v4.52 of EDIUS
