I'm experiencing issues when grouping a large amount of catagorical labels per edit, when using the build in grouping functionality released in the October 2016 release.
When I exceed a given amount of labels grouped in "one go", when finalizing and clicking "Ok" the "Working on it..." will appear, but be stuck. I'm unable to exit the process and the only way to gain control of the program again is by exiting the program completely from windows task manager.
If I instead group a few items at a time, everything works fine, but working like that would significantly increase my work time.
Suggestions to why this happens and how to avoid it, besides being a problem with the desktop client?
