Dear All,

I watched the following video http://www.ini.uzh.ch/~acardona/movies/arealist-create-and-edit.mp4 describing how to segment in TrakEM2 and at 43 sec, it demonstrates how to use polygon ROI tool to draw a ROI then use the FIT SPLINE option to get a perfect selection.
Unfortunately, using the last FIJI version available (ImageJ 1.49t), it impossible to use the polygon ROI tool which is not working anymore. Using it will just draw a tiny yellow square as a first point and refuse to add a new one, getting stuck. You can't even unselect the ROI easily.
I am not sure if it is due to an update of the plugin or of ImageJ.
The tool is working fine outside of TrakEM2.

Does anyone has a different experience or know how to solve this issue?
