I just installed 0.8.8 for subclipse, and the keyboard shortcut for compare with latest is not working in Team Synchronizing view. If I open up the Team Synchronizing view, synchronize with my SVN server, select one of the files with changes, and press Ctrl + Shift + C, instead of getting a compare I get an error message stating "Please select one file or folder which is managed by CVS or SVN". I do this regardless of what file or folder I select.
Note that this did not happen in version 0.8.7 for subversive - I switched SVN plugins.
Also note that this does not happen in the normal Java view of the files.
