After installing MouseFeed, the 'Expand All' button in the Team Synchronizing view is no longer functional.
Applicable to eclispe 3.4.2, but apparently not to 3.4.1
I experienced this too on Eclipse 3.5. Uninstalling mousefeed helped.
As I cannot reproduce the issue with Eclipse 3.5.2, the question: are you talking about the CVS Synchronize view or the SVN (subversive or subclipse) View? (The Sync View is unfortunately, not generic and every team provider ships it's own implementation...
I'm having the same problem with MouseFeed 1.0.0 under Windows 7 with Helios Service Release 2 (Build
id: 20110301-1815) & Subclipse 1.6.17 and also under Mac OS X 10.6.8 with Eclipse
Version 3.7.0 (Build id: I20110526-1708) & Subclipse 1.6.18
The problem with the Expand All button occurs under SVN Team Synchronizing perspective.
