It seems there is a problem with obsolete classes.<br><br>SystemNavigation default obsoleteClasses� -&gt; an Array(AnObsoleteWordArray AnObsoletePath AnObsoleteLine)<br><br>If you then browse WordArrayForSegment, you will see that it is a subclass from AnObsoleteWordArray. Changing that, back to WordArray, and then evaluating:<br>

<br>Compiler recompileAll.<br>Smalltalk fixObsoleteReferences.<br><br>SystemNavigation default obsoleteClasses� -&gt;&gt;&gt; an Array(AnObsoleteWordArray)<br><br>But I cannot get rid of that final obsoletClass. <br><br>

I tried inspecting SystemNavigation default obsoleteClasses and checking the pointers to the obsolete class, but I couldn&#39;t find anything.<br><br>BTW, issue 3864� is failing because of that.<br><br>cheers<br><br>mariano<br>
