Inconsistent break points in XBL source.

Venkman 0.9.85 FF 1.8B2 5/10/2005.

I get inconsistent display of XBL lines for which a break point may be 
set. I sometimes have to reload FF two or three times in order to set a 
breakpoint in a desired section. The access to lines also seems to 
change during execution. If I can get a breakpoint set in a location 
which actually breaks, I can then set other breakpoints. Access seems to 
be on an all-or-nothing basis for a particular method/property etc.

b.t.w The new feature which allows code stepping during a drag & drop 
operation is indispensable.
