Bug 64043 [Workbench] Ctrl-tab in maximized editor causes NullPointerException
Reported: 2004-05-26 03:18:15 | Status: verified fixed

I'm using 3.0M9. I just started the eclipse, projects and files are already open. I pressed CTRL-Tab to switch to the next editor, and got a dialog box for this error. The editor pane was maximized, and this error happened a few times. After restoring the editor pane, and maximizing again, the error does not occur. !SESSION May 25, 2004 23:56:18.985 --------------------------------------------- eclipse.buildId=I200405211200 java.version=1.4.2_01 java.vendor=Sun Microsystems Inc.
