EDIT

If linking is switched on in the navigator:

the TaxEditor slows down tremendously in large classificiations. I observered this e.g. in E+M Hierarcium taxa (but also others).

The reason is that the linking work synchrounously and runs very often.

Best solution would be to run it asynchrounously so it does not slow down at all. If this is not possible for some reason the data that needs to be retrieved needs to be reduced or the interval prolongued. Currently it is almost impossible to work with the link switched on.
