I hadn't noticed that, but maybe I have a different setting for shrunk 


This is with the very latest ERG "LinGO (30-Apr-05; SP2)". With this 
shrunk types setting, feature structures are quite manageable in size.

In fact, with *no* shrunk types, the feature structure window for the 
parse of "the dog chased the cat" still behaves itself -- apart from 
horizontal scrolling not quite reaching the most embedded part of the 
feature structure.

I do get bad behaviour for longer sentences, such as "the dog chased 
the cat that I saw in the garden", where it takes around 10 seconds for
