Hi Michael,

I think i maybe found possible memory leak/bug in latest beta.

What i did is i scaled up that model i sent you hour ago and i scaled it 100x (to be bigger) but my export settings OBJ left on last used when object was smaller so i had angle set to 3 and divide to larger than 2 so Moi started generating poly-count, it took minute or so and it was processed to 22% and it already used 38GB of System RAM so i concluded it won't have enough ram to finish operation and then I canceled export. BUT my MOI is even 5 minutes later still not properly responding properly and GUI is slow and staggering, Memory usage oscillated from initial 38GB at processing back to 1 GB and then go up to 5GB (now is at 7GB while i type this message so it's been 8 minutes since i clicked cancel and popup window closed) but my CPU usage is still 1-2% (1 core used at full/max).

Since you have that model (NDA) you might wanna try do that to see is it memory leak or some other kind of bug.

cheers
