TableView's CollectionNavigator sometimes doesn't work right

[tig]

I can't always reproduce this (like right now), but sometimes the Scenario List in UI Catalog doesn't respond to collection navigator keypresses correctly.

When this happens, the category view works fine but the scenario view refuses to coopeate. Pressing b for example goes to some random scenario instead of Bars.

If anyone encounters this while in the debugger please try to debug!
