I get an error message with

SetOptions[RegionPlot, ImageSize ->  Medium];
RegionPlot[u v (1 - v) >= 10, {v, 0, 1}, {u, 0, 100}]

that says

Join::heads: Heads List and Rule at positions 1 and 2 are expected to be the same. >>

That message does not occur without the SetOptions line. Any clue as to what is going on ? (This happens in 9.0.0 and 9.0.1 Mac).

  • $\begingroup$ Thanks to all, I reported this as a bug. Dunno if Wolfram will update 9.0.1 though. $\endgroup$ – A.G. Dec 26 '14 at 23:30
  • $\begingroup$ It seems this bug is resolved with MMA >=10.0? @Mr.Wizard $\endgroup$ – user9660 Jun 7 '16 at 15:23
