0xC0000005: Access violation reading location 0x3f800000

[Narf the Mouse]

I'm testing out Newton and Ogre 3D together (using C++). I've got all my code set up and it compiles, but the instant after Ogre3D starts (and in Newton.dll, I tracked it), I get this error:

Unhandled exception at 0x3f800000 in NewtonAndOgreTest.exe: 0xC0000005: Access violation reading location 0x3f800000.

Solved; I was using evt.timeSinceLastFrame when I should have been using GetTimeInMicroseconds().
