OB System Browser worked at first try and looks exciting. (I've already
fixed what looked like a type error)

What type error?</pre>
</blockquote>
It was the classical Smalltalk error: an uninitialized inst.var. (nil
instead of a Boolean).<br>
<br>
The error occurred when I first opened OBSystemBrowser. <font
color="#ff0000"><b>hasChanges </b></font>was nil when it shouldn't
be; I think this was the failing method. <br>
<br>
OBCodeBrowser>>stepAt: milliseconds in: aSystemWindow<br>
<b><font color="#ff0000">hasChanges ifTrue:</font></b> [self
signalRefresh].<br>
self clearChanges<br>
<br>
I added<br>
OBCodeBrowser>>initialize<br>
<i>" Missing method. Type error: hasChanges not always set. "</i><br>
super initialize.<br>
self clearChanges.<br>
<br>
A comment: I like to add an empty <i>initialize</i> method to Object
so
that all other initialize methods can start with <i>super initialize</i>.<br>
<br>
Cheers<br>
