Ah, that's an interesting example.I hardly use the component registry

So was the issue fixed?
I'd suggest to renamed your MClassess to MDgClasses or not to use MSEgui at
all. The best approach here is to rename only 1 collision at a time - at
least this is what I would do. The fix is pretty easy - renaming the file
itself and all uses section of units that are using it. (prevents updating
to D2010 for namespaces)

I doubt that Martin would agree to rename his MClasses to MSEClasses, since
more people is using the library (that's my guess).

Is there a risk of bloating the program by duplicatrd code? It sounds to me
that Martin's and yours MClasses are doing pretty much the same thing.
With Namespaces such code duplication will become very welcomed.
