Hello,

I sent (and received) the following messages a couple of months ago

-HI,
-Looks like there is no work-around for this
-particular bug. Plotting uses the correct
-bounds, but scaling uses the wrong one.
-I will try to do an update soon.
-Sorry for the trouble, -TC

I'm just checking to see if these problems have been corrected in the
latest release (0.87.3).

Thanks,
Derek
