Hello,
Since I'am tight with my schedual, I've uninstall the CW, and re-install it again, and the probelm has disappeared.
I think that, since preior to 10.1.8, I've installed in my computer CW 10.1.3, but never uninstalled it, and this might be the problem.
Anyway, I'll send SR on this issue in case that my susspecious is not real.
