Hi!
Am I the only that that is experiencing that Ctrl-dragging interface items around doesn’t work in ZBrush 4?
I’m on Windows 7 64 Bit…
Ctrl + alt dragging now
Thanks murray!
Just saw it still stated “Ctrl-dragging” in the ctrl-help display, tried Shift and Alt, but no combinations… silly …haha, simple 
Just purchased Zbrush 4, and the tutorial vids don’t tell you this! I’m glad this was answered here, but maybe they could update this bit of information?
This information is mentionned in the what’s new guide of ZBrush, page 15, in the first chapter “Notice for previous users of ZBrush” 
To customize your interface when Preferences >> Custom UI >> Enable Customize is on you will now need to hold CTRL+ALT to move any interface buttons.
