I have an odd problem and was wondering if anyone had some insight to
my issue.  I have some code which appears to run perfectly fine under
normal conditions.  I can run multiple iterations w/ no issues what so
ever.

However, if I...
- pause code execution
- view Locals
- expand the Locals tree to view a variable that is an instance of my
own class
- then attempt to resume execution
...the code will fail with Error 91 (Object variable or With block
variable not set)

Furthermore, if I click on Debug in the error window, no failure point
is highlighted in the code (side note - I do have the debug option to
break in Class Modules).  Code remains in the break state.

My code is somewhat complex so I'll hold off on posting the code for
now.  What I initially want to know is if there is a common
explaination for this type of failure.  I'm hoping that will point me
in the right direction so I can find the problem.

One more point - I am using the published hack to create my own
collection classes (actually, I have a heirarchy of collection
classes).  The code fails only when I expand the expression which is an
instance of my collection class.

I am using Excel 2003 SP2.

Thanks,
