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

((ARGS SIGN) (HD-DTR HEADED_PHRASE) (NH-DTR BASIC_BINARY_HEADED_PHRASE)
  (DTR LEX_RULE_SUPERMOST))


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 
the window to be displayed, and it comes without a vertical scroll bar. 
But I don't get any strange artifacts in the window after resizing.

I was thinking that perhaps Emily was seeing her LKB session getting 
bogged down because she didn't have enough memory in her machine? I 
have 1GB in my powerbook G4 667HMz and it all seems to hum along quite 
happily.
