SPE editor slow?

[timmy]

hello i've been using the SPE editor on a moderately large project and 
it's constantly pausing during editing, like it's attempting to check 
something as i edit.
as you can imagine a 4 second pause every few characters is EXTREMELY 
annoying when you just want to get some work done. i really like SPE's 
layout and features but if it's going to be dogshit slow all the time 
i'll have to change. please help!
