There is a serious bug concerning editing .cpp files in Eclipse. If a .cpp file is open in the runtime workbench, when you subsequently try to run the workbench, the following error pops up: "Error notifying a preference change listener. Check the log for details." Clicking "ok" makes it pop-up again and again. There is nothing you can do to use the workbench after that. Here is how to reproduce the bug, Create a c++ project and then a .cpp file. open the file so that it's open in the editor. Close eclipse using File > Exit. and then re-run the runtime workbench. Here's the error log: !ENTRY org.eclipse.update.configurator 2006-06-07 14:43:26.484 !MESSAGE Could not install bundle plugins/org.eclipse.hyades.execution.aix.ppc_4.2.0.v200605251528 No

This is a pretty common workflow that almost everyone working on the CDT does daily. What is you version line up? Was this a workspace created by an earlier version of the CDT? What else do you have installed (is this Callisto?). I remember seeing something like this earlier in the release which was fixed.

I'm using (cdt 3.1.0) and an eclipse build from March, which would explain why I don't have the fix yet. thanks. (fyi, I was creating a new workspace/project with these versions.)
