I have a DLL that has been created in VB6. It works with norml VB6 exe
projects.

When I look at the object browser in Excel it shows all of the classses
as being exposed. Excel even allows the quick complete of properties
and methods within the DLL. However as soon as the debugger crosses
the line with the first piece of code it simply crashes. It doesn't
crash the whole of Excel, it just stops the step though within the VBA
code.

No erros, I have an error handler and the options turned to break on
all errors.

The DLL is in the references as well.

Any ideas?
