OpenGL in 64bit M4L issue

Hi everyone,

I'm currently working on a MaxForLive quad panner that makes use of the physics engine, with a 2d visualization / UI running in OpenGL (patch attached). The OpenGL & jit.pwindow part doesn't work inside 64 bit Ableton Live 9.1.1 & 64 bit Max 6.1.6 running on a late 2013 MacBookPro (Mavericks). It does work when I open/edit the device in the editor. I have also tested this on an almost identical spec'd MBP, with the same issue occurring.

The device worked fine when I tested it on an older MBP and a MacBook Air, both running 32 bit versions of Live 9.1.1. & Max 6.1.6.

So, is the issue really 32 bit vs 64 bit? Will I just have to work in 32 bit for this device or is there anything else I could do? Is this an OpenGL limitation?

I'd appreciate any ideas or pointers in other directions.

Thanks!

JM
