Comment 1 for bug 378228

Problem is apparently related to the SCIM application.

I saw a similar problem when switching from gedit to a shell window. The SCIM rectangle pops up on the bottom right side of the screen each time I switch windows. If I select SCIM option to not show this window, when switching from gedit to shell, the shell will ignore keyboard input as if it lost focus.

I tried removing SCIM, but then I was unable to type ê composed characters. But reinstalling SCIM, I was again able to type ê but all problems where back again. The problem is thus not related to eclipse but to a loss of keyboard focus when front most window is changed.
