Hey,
I just switched over to xp64 a few days ago, and have sense run into an issue in zb that’s never happened to me before. Whenever I ctrl+shift+lmb on a polygroup instead of it hiding all the other groups the top subtool gets deleted. If I do this on a subtool that’s not the top one, the top will still be deleted from the list, but will remane visible in the viewport.
Any ideas how to fix this?
Have you installed any plugins? If so, try launching ZBrush without them and seeing if this resolves the problem. If it does, then one of your plugins is at fault. To do this test, double-click to launch ZBrush and then immediately hold Shift until the launch completes.
Also, check any background processes that you have running. It’s possible that something is interfering with the way ZBrush is reading your key commands.
