Comment 43 for bug 43066

Moose,

It is true that Craig's solution does not work with libwnck22 1:2.30.0-0ubuntu1. However, you can add Maverick repository and force libwnck version to 2.30.5. This may cause version consistency issue with some packages later, hence not recommended, however I was able to the get the vertical window list work properly in Lucid.

Like others said, this problem has been around for years, and still no fix.
