title: Step Filter Icons Are "Greyed Out" (deactivated)
body: <p>Right up front:  I am new to Aptana Studio 3 and am still exploring how to use.  Most recently,
  I downloaded and installed it and right off the bat,  I noticed that the Step filters are shown as being "greyed out"  (deactivated).  I have read many, many Google postings put up by others who have experienced the same problems and I have read every FAQ I can find  and I have tried to implement the "fixes" that I found in the postings.  So far, nothing has worked and I am left not being able to use these critical Step filters.  I would appreciate any and all comments and suggestions which might help me to discover how to turn on/activate these step filters.</p>
  
  <p>Baseline information:</p>
  
  <p>Aptana Studio 3, build: 3.2.2.201208201020
  Build: jenkins-studio3-rcp-master-210 (origin/master)
  Date: 20 August 2012, 10:22:09
  Firebug 1.11.0 installed
  Operating system used:  MS Windows 7 Enterprise  version 6.1.7601 Service Pack Build 7601</p>
  
  <p>What I have tried thus far:</p>
  
  <p>(1)  Create break points in the javascript being tested
  (2)  Made sure that the Debug view is activated  (Windows--Show View--Debug)
  (3)  Run Debug</p>
  
  <p>Console messages:</p>
