Xdcam high res trasferring pauses when use Proxy on timeline

[Rudy]

Hi, I used edius 5.5 on an HP EliteBook 8540w with a Sony Xdcam PDW-HD1500 connected by ieee1394 and I had never experienced problem.
I need to be fast and so I use to edit proxy on timeline while Edius is importing high resolution.
Now with Edius 6.02 I can't do it because if I play or move cursor on timeline, importing process get pauses.
I turn off realtime DV out but nothing changes.
Anyone can help me? Thank you.

If pause backgorund job on playback is enabled it will do that.
