Corrupt Taskmanager

I use XP pro. My taskmanager is corrupt. Windows doesn't crash or anything when I use it, it is just that I can't change to the different tabs or anything because simply they do not exist. I can still end processes through taskmanager but I also want to look at the tab for network traffic and CPU usage. Any quick ideas on how to fix this? I don't want to do a major chore like reinstalling windows but if you can think of a fairly quick fix that would be helpful.

 

Its not corrupt. Double click the outer edge to get the tabs back.

 

that simple? cool. Been an annoyance for a while and haven't cared to fix it. Thanks.
