Operating system: Windows 10  
Slicer version: 5.2.2  
Expected behavior: Bone thickness map Extension complete execute  
Actual behavior: did not execute

I used the bone thickness map extension on my mesh in 3Dslicer version 5.2.2. When I click execute button, it did not start executing and my mesh missing from the panel box.

Previously with the same step on the same mesh using 3D slicer version 4.1.1, it did execute successfully. Why it cannot be done on latest version 5.2.2 and 5.2.1?

I dont really want to use version 4.1.1 because the crop box is thin and difficult to use.

With this fix it should work in 3D slicer version 5.10. ["Color Scalar Bar" reworked and upgraded, now it’s called "Color Legend" - #12 by Mik](https://discourse.slicer.org/t/color-scalar-bar-reworked-and-upgraded-now-it-s-called-color-legend/21567/12) .
