Thanks. This was with one frontend? And what was the exact sequence of commands used to replicate this? Sorry, but I need precise details of how you reproduce this, especially since I can't reproduce it. I'm pretty sure there are multiple issues here, one of them is fixed by my vb2 patch, but this page fault is almost certainly a separate problem. Based on past reports there is also a possible problem with multiple frontends, but I don't have hardware like that and even if I had I am not sure I would be able to test it properly. Besides, that issue seemed to be unrelated to the vb2 conversion. It's all pretty vague, though. Regards, Hans
