[Zach Pearson]

I think the VR mouse modes just need some guard code around them. They can be enabled at any time, before the segmentation tool is even opened, so they check for it and do nothing if they can't find an open instance of it.

But between it being created and switching to the VR mode, it can also fail to have the 3D cursor.

Maybe it should spawn the 3D cursor regardless of what mode it's in and then hide it when Desktop 3D or VR isn't the current mode, or maybe the mouse modes need a if hasattr(..., segmentation_sphere, None):

[Zach Pearson]

Should be fixed tomorrow. I added guards around all the modes so that they look for the tool and return without error if they don't have it.
