Hello,

I'm trying to draw a sphere ROI using the Draw ROI plugin option. However, I can't seem to draw the actual ROI. I'm using a Mac and I know there are some issues with this, but I also know I've done it before using the 'pen' option. Right now, the 'pen' option is greyed out and thus cannot be used. Anyone know of a way to turn this option on?

Thanks,

Amy
