I have creating custom Shortcut Keys for my brushes and it did respond to the keys until I click out of zbrush 4r7 and click back into zbrush 4r7. I tried relaunching zbrush 4r7 and loaded the saved custom keys and it is still not responding to the pressed down keys I have assigned it to originally.
However, when I hover over the brushes that I assigned custom keys to, the shortcut key is visible when the display box appears. But it does not activate when the button keys are pressed. How can I fix this annoying issue???
