I’ve had this for ages on SBPro but put up with it, but can’t see why it’s happening on Harmony as well.
Any time my pen gets near my Cintiq the canvas rotate tool disappears when pressing command-option. It’s there on pressing the shortcut, then blinks out when the pen goes anywhere near the screen. Any ideas why this is happening? Is it a Wacom issue or a ToonBoom fault? I get around it on SBPro usually just by using C/V if I need to but I don’t know the Harmony shortcuts. Seems a bit of an essential tool to lose out on.
