Comment 6 for bug 642746

I have noticed this one too.

I use both karmic and Lucid in addition to testing Maverick.

I have a 32 pixel wide "frame" around the edges of my monitor; to stash all of the launchers, etc. In both Karmic and Lucid, a workplace switcher placed in a vertical panel orients itself vertically (i.e. stacked on above the other) as a single row.

After a fresh install of Maverick into its own partition, the workplace switcher was located in the bottom panel. As soon as I moved it to the left side; things got strange. Instead of being vertically stacked, the switcher screens were horizontally stacked.

All I can say is - something broke!
