Comment 3 for bug 856138

This also might have something to do with mouse events, I don't know, but anyway I can affect this by how fast I clickc the icons in unity panel.

If i click nautilus panel slowly for example, it gets frozen in active state: http://www.foopics.com/showfull/e3ac3d363789734d4335b0e56ffe111a

However, if I click nautilus icon very very fast, it gets frozen in inactive state: http://www.foopics.com/show/74dc8f831c3154961c8346a4f2a2cfbf

Neither way, it never responds to hover or changes state anymore, frozen.
