Freeze while light cache calculation

[elivnA]

Ever since switching to sp3, i've been getting these strange freeze-ups in scenes, without any apparent reason, when it wants to calculate lightcache.. Now i just discovered its when you accidentily select a (less than?) 1 pixel area with the new region render feature. When vray stops responding, you can still use max, but anything you save becomes corrupted, and the viewports no longer work.

It took me a while to find out why this happened, so i thought maybe other people were having this problem as well? I'm using sp3a.

edit: ah, looks like people are: http://www.chaosgroup.com/forums/vbu...ghlight=region

Never mind :P
