[ESS] Error in assign(".Last.value", .ess.lvsave

[Ross Boylan]

I've been getting this message sporadically when I run R under ESS:
> Error in assign(".Last.value", .ess.lvsave, envir = baseenv()) : 
	cannot change value of locked binding for '.Last.value'

I haven't noticed a pattern to when it appears; it is erratic.  I've
been seeing it for awhile now, perhaps since upgrading to R 2.4.

Can anyone illuminate what's going on?

Thanks.
