Title:
  Enabled "Show position of pointer when the Control key is pressed"
  option in g-c-c makes windows lose focus when CTRL key is pressed,
  which breaks multiple-select using CTRL+CLICK in some applications

Status in Unity:
  Confirmed
Status in “unity” package in Ubuntu:
  Confirmed

Bug description:
  Many applications use the CTRL+click combination to enable multiple
  selection.  It appears that some system component is stealing focus
  when the CTRL key is pressed, which breaks this for some applications.
  In particular, multiple selections no longer work in the Eclipse IDE.

  To repeat (quick method): open a terminal and click in it to give it
  focus.  Notice that the text cursor is solid.  Press the CTRL key and
  notice that the cursor becomes a open rectangle.  While holding down
  the CTRL key, press a mouse button and notice that nothing happens.

  For more details about what is going on, you can also use the "xev"
  application as follows:

  (1) Start "xev"
  (2) click in the xev window.
  (3) press 'a'
  (4) press the CTRL key (notice that focus is lost).
  (5) release the CTRL key.

  Here is the output from the above sequence (starting with pressing the
  'a' key):

  KeyPress event, serial 41, synthetic NO, window 0x5600001,
      root 0x29a, subw 0x0, time 112920954, (61,102), root:(1561,154),
      state 0x0, keycode 38 (keysym 0x61, a), same_screen YES,
      XLookupString gives 1 bytes: (61) "a"
      XmbLookupString gives 1 bytes: (61) "a"
      XFilterEvent returns: False

  KeyRelease event, serial 41, synthetic NO, window 0x5600001,
      root 0x29a, subw 0x0, time 112921054, (61,102), root:(1561,154),
      state 0x0, keycode 38 (keysym 0x61, a), same_screen YES,
      XLookupString gives 1 bytes: (61) "a"
      XFilterEvent returns: False

             0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

  The problem that I was experiencing with Eclipse can be repeated as
  follows, although I am using some non-ubuntu components so it may be
  less useful to you.  I am using Juno SR1 as downloaded from
  eclipse.org with an Oracle 1.6 JVM.  To repeat the problem, do the
  following:

  (1) Select Window>Show View>Other...
  (2) Click on "Debug" to show the debug related views.
  (3) Click on "Breakpoints" and notice that it is highlighted.
  (4) Hold down the CTRL key ("Breakpoints" is grayed out)
  (5) While holding down the CTRL key, click on "Display".  Nothing happens.
  (6) When releasing the CTRL key there is a cute animation (from Unity) and the "Breakpoints" view is re-selected.

  When used on other system, this sequence would have allowed me to
  select both the "Breakpoints" and "Display" views in one operation.

  Thanks!
