Initial "Make Component" takes excessively long time (SU Pro 2017)


Problem still exists in v2019 on Win2010. SU was installed as admin.

File with 400 components and 700 groups. Tried to create a new component from some edges+faces. Result: spinning wheel of death etc. After a few minutes manually killed SU using the TaskManager.

Should be easy to reproduce I guess and high on the to-do list imho.

Edit: first making a group of the entities and closing the Outliner before you convert the group into a component seems to work.
