The "Search Results" windows doesn't show the search results, instead showing whatever window was at it's location before. The same goes for the Tool Results window, but that one is ok after I run a tool. Docking or undocking doesn't help.
It could be a driver issue (nvidia quadro fx 540, XP Pro), although I don't have any other issues.
What the... today it works?? I'm not sure what solved my problem, maybe turning on the "auto-hide" feature for the Search results/Tool output, then restarting TP?
