After you start Multilanguage from the tools menu in visual studio visual studio becomes the topmost foreground window. Even after you close Multilanguage dockable window this remains the case.
I cannot get anything in the foreground anymore. The only way to resolve this is close and reopen visual studio. A side effect of this bug is that the help about screen in Multilanguage is opened behind visual studio. Then it looks like visual studio hangs because the screen is in the background.
Could you remove this behavior?
