[Camino] Opening new windows in Tabs

Hi,

I've set my Tab preferences to "Open tabs instead of windows for:"
"Links that would open new windows" (as well as the others). This
seems to work for a while, however, when I restart Camino the  
preference gets
reset. When this happens the behaviour reverts to opening new windows in
new windows (instead of tabs).

I was using Version 2007052622 (1.6a1pre), and I've also just tried  
today's
nightly build and the issue is still there.

Is this a known issue? Is there some way around this?

Thanks,
Igor
