How can I prevent lookup editor from converting greater-than, and less-than characters to escape chars?

[timgren]

Lookup table fields that contain < or > symbols are getting escaped to &amp;gt; and &amp; lt; 

How can I prevent this from occurring? It only happens when manipulating the field value using lookup editor. 

For example: 
servicecode>="200" AND servicecode<400,1,0), failed=if(servicecode>400,1,0)

gets rewritten as: 
&amp;amp;gt;="200" AND servicecode&amp;amp;lt;400,1,0), failed=if(servicecode&amp;amp;gt;400,1,0)
