[Scilab-Dev] scinotes bug?

[Sylvestre Ledru]

Hello Dean,

Could you use the bug tracker ? (even if you are unsure that it is a
bug)
http://bugzilla.scilab.org/

It helps to keep track of the various issues and many conversations in
the Scilab community are taking place on the bug tracker.

thanks,
Sylvestre
