I saw this exception several times. But I do not know the cause. Last operation I did was close opened files using middle mouse click on tabs. java.lang.RuntimeException: WARNING: Prevented recursive attempt to activate part org.eclipse.cdt.ui.editor.CEditor while

Dmitry, any idea about this one?
I'm seeing this as well. I also saw an issue whereby the build console was recursively bringing an editor to the front. Every time the new user closed the editor, and selected anything int he C/C++ projects view, the editor reopened. I notice that "show error in editor" is checked by default, and this could be part of the problem...

Every time the new user closed the editor, and selected anything > int he C/C++ projects view, the editor reopened. I think you are talking about bug 306388 (which could be related). Could you elaborate why your issue is "recursive"? Are you seeing this exception?
Yes, I am seeing this exception. And by recursive, I meant it was impossible for this user to close their editor and keep it closed. They had a debug console which has focus, so weren't even aware that the hidden build console was the cause of the editor reopening.
