Ctrl+S problem in Mac

[kabeh13]

I use Zbrush 2021.1.1 and recently I upgraded macOS to Big Sur 11.2
but now i have these problems:

in full screen mode, Save as (both tool and project) does not work, i have to use
Command+Tab to move out and come back to see the save window.

Ctrl+shift+s (for saving tool) does not work properly, one time it works and the exact next time it just change the brush size (like I press S)

anybody experience this problem?
does updating Zbrush solve it?

Hello @kabeh13

Please upgrade to the most up to date version of ZBrush. The upgrade instructions can be found here. If that does not resolve your issue, please contact Pixologic Support .
