Hi guys, This is the second time this has happened to me, after setting up a completely new workspace the first time the problem occurred. A nasty bug, because it makes Eclipse unusable, meaning I have to fallback to some other IDE :( ENVIRONMENT =========== MacBook Pro running MacOS 10.4.7 ECLIPSE ENVIRONMENT =================== Eclipse 3.2RC4-macosx-carbon with CDT and Subclipse plugins installed. PROBLEM DESCRIPTION =================== 1. Import source code from Subversion repository. 2. Work on source code, commit changes. 3. Quit Eclipse. 4. Restart Eclipse, following error message: "Error notifying a preference change listener. Check the log for details." 5. No matter how often one clicks "OK", the same error message is displayed. Have to kill Eclipse to get out of the nasty loop. STACK TRACE IN SYSTEM LOG ========================= !ENTRY org.eclipse.ui.workbench 4 2 2006-07-11 10:23:01.036 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

Updating Eclipse to 3.2 (from 3.2RC4) and CDT to 3.1 seems to have solved the problem. I tried updating CDT before submitting the bugreport, but was not using the most current update site (http://download.eclipse.org/tools/cdt/releases/callisto). My bad, sorry. Thanks for the assistance, Heinz.
