In the recent Build (45996) available to download (oficial build), the Recursion option for the Bevel (amount of subdivision of the Bevel tool) is unavailable at the Mesh Tools Panel.
Thank you and wow ! Ultra Fast answer !
I tought it was a bug because I have been testing in Win/Mac/Linux and the option is unavailable (but documented as a feature) for all of the O.S. I'm seeing that the Status for the bug report is ''closed''.
Thank you Sergey Sharybin ;).
