I don't get this error in Win98 either.  My guess is that it's your
video driver; I don't know why this would happen in 1.7.0 and not
1.6.2, but lattice has changed, and it might be doing something now
that uncovers a bug that was hidden before.  The address of the error
is in R's graphics driver code.

Could you try to see if there's a newer version of your driver
available, or try to see if you can reproduce the bug on a different

Another thing that might work is to set options(warn.FPU=TRUE).  This
will enable checking whenever you load a DLL (which many library
packages do) to see if the floating point control word has changed.
If your video driver is messing with it (a common kind of bug), then
you'll likely see warnings popping up.
