I cannot reproduce this with either the latest stable or current development versions of Blender:

  • Please download the latest build from
  • Go to File โ†’ Defaults โ†’ Load Factory Settings and then load your file to see if you still can reproduce this issue.
  • Also: is there anything in your OS capturing the Shift key for some reason? [do other programs still permit Shift+modifier commands?]

More than a week without reply or activity. Due to the policy of the tracker archiving for until required info/data are provided.

Yes, this happened to me too. Strangely enough, clicking on another software tab and coming back in Blender "fix" the issue but not really. As soon as I press shift, it doesn't work anymore. Once shift and MMB has been pressed, all it does is zooming. It was working until some point. Also using a Mac Pro.

So if i get out of blender to display another app then go back in Blender, the MMB button pressed alone do rotate, but as soon as I press shift, alt, ctrl, or cmd: it zoom when pressed. Then all it does is zoomed even if MMB is pressed alone. The scroll doesn't respond anymore either.

Loading factory setting didn't resolve the problem.

I wonder, but I am not sure, if the issue started after I used the Wacom for some sculpting.

did you guys fix it?

because I have it too and I can't fix it in any way
please help

HEY GUYS I JUST FIXED the problem it was the (Wacom applications)

if you get rid of them it fixes the problem

Awesome! @Eddie (egorsurfer) I fixed but didnt know which of all applications was messing with me I just reinstalled the wacom aplication and others and done fixed. But at least its good to know it was the wacom app all along. Thanks

Yes, reinstalled the Wacom latest driver and the bug disappeared. I hope it won't occur again if i want to use the tablet. Sculpting is more fun and intuitive with the stylus.
