When the patch of bug 574036 is applied, a new context menu (a menupopup) is added to the WebConsole. This menupopup holds a menuitem defined as follows: menuitem.setAttribute("label", this.getStr("copyCmd.label")); menuitem.setAttribute("accesskey", this.getStr("copyCmd.accesskey")); menuitem.setAttribute("key", "key_copy"); menuitem.setAttribute("command", "cmd_copy"); It is expected that the menuitem is automatically disabled when there is no selection, just like the Edit > Copy menuitem. However, on Linux this does not happen. (this is a follow-up bug report, on solving the problem with the menuitem behavior on Linux.)

is this linux only or are we seeing it on other platforms?

Initially, it did seem Linux only. However, once we pushed the test code into m-c, we also saw failures on Windows machines.
