But this will only compare the lowest level subclassed and might gloss over properties set in perhaps different superclass hierarchies?
Or programmatic changes with addproperty() on the fly?

@Al:
I think it has to be handled at the instantiation level, some simple checking with amembers() and some logging or the diff could also be handled programatically...

>>I'm doing some maintenance programming. I have 2 container classes, each of which contains a grid. Within the first column of each grid there's a dropdown combo control.
>>
>>I have an appearance issue with one of the dropdowns (see attached image). If the dropdown has the focus, the colour scheme is such that the text of the item is not visible. If the focus is elsewhere, the selected value in the combo can be read as expected. The other combo does not have this problem, its text is visible even if the combo has the focus.
>>
>>My main goal is to fix this issue, so if anyone has a suggestion specific to the use of combos in this scenario I'd appreciate it.
>>
>>But, in general this is part of a larger maintenance issue. In this particular case the combos are two different subclasses of the same combo class. It would be nice to have a tool that could gather all PEMs for both classes and highlight the differences. Anyone know of anything like that?
>>
>>It would be helpful in those cases where the client says "Make item X work the same as item Y".
