Thanks for that recommendation, I really do use subversion for some time. 
But how can I use it to solve this problem? I do changes to the common 
baseclass which is OUTSIDE my development. I quite correctly assume that 
the developers of the classlib also use Subversion, alas, having no public 
access.

So HOW can SVN be of any use for THIS prob?
