Created attachment 230100 [details] screenshot at step 6 OS: All (confirmed on Windows 7, RHEL 6, Mac OS 10.8) JDK: Windows/REHL: java full version JRE 1.7.0 SR3 IBM Windows AMD 64 build Mac : Oracle JDK 1.7.0_17 Locale:Japanese/English Steps to recreate problem: 1- create a simple project 2- create two simple files, file1.txt and file2.txt 3- enter text in file1.txt 4- drag file2.txt tab and drop outside eclipse window to place it on a separate window 5- enter text in file2.txt on a separated window 6- press Ctrl+Z for undo Expected output: text entered in file2.txt is undo. Actual: text entered in file1.txt is undo. Similar problem occurs about other Edit shortcut like redo, copy/paste. The same problem happens using menu on main window. Only these operations using context menu work as expected.
Works fine for me using our latest build: http://download.eclipse.org/eclipse/downloads/drops4/I20130423-0800/
(In reply to comment #1) > Works fine for me using our latest build: > http://download.eclipse.org/eclipse/downloads/drops4/I20130423-0800/ reproduced using I20130423-0800 Mac OS X 64bit cocoa build and I20130425-2000 Windows 64bit build. (we are using Japanese locale) This problem occurs on Windows/Linux/Mac, but this does not easily be reproduced only on Windows 8 while it can be easily reproduced on other platforms like Windows 7, RHEL and Mac OS X. On Windows 8, this problem occurs only when clicking Tab of editor view or clicking a frame of separated window in order to move a focus on the separated window. If you click at a place within editor view and do Undo (Ctrl+z), this does not happen.
I still cannot reproduce this on Windows 7 (In reply to comment #2) > (In reply to comment #1) > > Works fine for me using our latest build: > > http://download.eclipse.org/eclipse/downloads/drops4/I20130423-0800/ > > reproduced using I20130423-0800 Mac OS X 64bit cocoa build and > I20130425-2000 Windows 64bit build. (we are using Japanese locale) ^^^^^^^^^^^^^^^^ Did you mean N20130425-2000? The steps you use are exactly as in comment 0? e.g. > 4- drag file2.txt tab and drop outside eclipse window to place it on a > separate window What exactly do you mean by "separate window"? Can you attach a screen shot?

About "separate window", I mean a window detached from the original eclipse window. Please see attachment 23011 [details], "SeparateWindowTest2.java" is corresponding to "file2.txt" in the procedures.
