Any thoughts on the firs thing I should check when RegionPlot3D is giving me a blank graph? When i change what I'm plotting I get an actual graph.

@andrew: you can check if any polygons showed up by executing Shallow[First[%]] after your plot.

Hey guys, I am facing a weird issue with Mathematica, but wasn't sure if I should post as a question or not.

I have 2 installations: One on Mac OS X (MMA version 10.0.2) and another on Red hat Linux (MMA version 10.0.1)

I have two identical notebooks that uses a set of packages, I checked md5sum for both notebook and packages on both systems they are bit-by-bit identical.

The notebook and package have some compiled functions

When I run both notebooks, I get different results, especially for a parameteric plot and a FindMininmum execution.

The Redhat notebook (on version 10.0.1) yields the correct answers and plots ...

Have you ever seen anything like that before?

@Bichoy are you using FindMinimum with a fixed random seed, or alternatively with the same starting point each time?

@Guillochon I'm pretty sure this setting does not exist. I'm very interested in seeing a specific example where the coloring in V10 is not as good as in V9. Could you give an example?
