This is from EON tech support:

Quote " We have identified and fixed potential memory leaks regarding Poser import today, but if the problem is not specific to Poser, another problem might still be there. We double checked the code for free resources evaluation, and it is indeed working like in Vue 5 and early Vue 6 builds, so the problem is not related. This is therefore probably some memory leak regarding undo/redo history or something like that."

I posted this at EON & in another thread here also - for those who just go there.  Relief is in sight!

I thought it best to start a new thread so it wouldn't get buried any further.
