Dear Michael,
We make no association and if you remove the Syncro SVN Client installation directory you should have no left overs (there are no files that we copy some place else).
Sometimes Java applications on Mac have a certain problem that the icon used in a message dialog remains the last one used in a previous application so this could be your case. There is a probably a cache problem in Java.
Can you try to clean the Java cache and then have a go?
http://www.nau.edu/~d-elearn/support/tutorials/java/mac/cache.phpWhat is the new application you are using? Is it Java based?
Can you send us a screenshot?
Anyway, if you dragged our client to Trash, it is just the icon from our application and not the functionality.
Regards,
Radu
