Hello,
We cannot reproduce the behavior you described. Please give us more information about this like the operation system used, what kind of protocol you use to access the repository (svn, http ...) or the Java version used to run Syncro SVN Client. You can find this in the Help menu, About dialog, System properties tab, java.version entry.
Also we should look in a log file generated by the SVN client when the "Show History" or "Compare with" actions are invoked. Please
contact us on the support email address to give you instructions about enabling logging in Syncro SVN Client.
Best Regards,
Octavian Nadolu
