[ImageJ-devel] Bug in ImageJ2 ?

[Michael Zinsmaier]

Hi Curtis,

I updated to the snapshot-core.jar and it works now as intended. We will 
release an updated (ImageJ4 beta compatible) version of the ImageJ 
plugin in the next few weeks together with the next minor release of the 
Knime Image Extension.

Thank you for your efforts
Regards Michael
