I recently bought a dual head Matrox G 450 PC video card(for two monitors).
I've found a little problem.
In OS display mode (vs Pulsar mode) The "edit Mode" button of the project explorer can not be held, and you are unable to do any edit. But, in "normal Pulsar" display mode, it works fine.
Any idea?

This may be of some help.
I bought a Power Sampler last weekend and installed it with the latest LUNA software. Nothing would work. After a weekend of frustration I found that switching off the duel monitors on my MATROX450 solved the problem.
I'm now looking at downloading the updated matrox driver/software.
