We are having a weird problem with the noise level limit tick.
We bought 2 workstation licences of Corona 1.5.2, in one of them its working properly on the other its always off and the we cant change the value. We tried to check if adaptivity was off but in this version the experimental stuff panel is no longer in the development panel.
We already tried to re-install.
So we are kinda in a dead end here.
Dev options are still there, but changed with the organization to have the System Settings tab - under System tab, click System Settings button, and check the Enable devel./debug mode. Then head to the Performance tab, and the dev settings are exposed there. Does sound like Adaptivity could be off as that would disable the noise limit option. Let us know if that is the case or if something else is happening here!
