(Instead of hiliting I should have written high-lighting.........I must have taken hiliting from the hi-lite pen brand. oops)
Now that I am back in OSX 10.2.6 - I think you've found a nasty bug - as I have just come across the same situation doing what you did........interesting that going out of metro and into safari to write this, and back into metro removes the highlighted menu but the problem remains. Quitting metro doesn't seem to get you out of metro although it did ask if I wanted to save changes. Force Quit does.
Explaining the steps.......or the guide for HH to avoid the bug he's found......
Adding reverb to an audio track.......
- place some audio on track 1 (or any other track number)
- do a command 9 & a command 0 (zero) to bring up the plugins and effects windows (or open them from the "windows" menu).
- make sure the track window has selected track 1 (or whatever the track number was in step one!)
- go to the plugins window and drag AUMatrixReverb across to the effects window
- play the track by hitting the space bar or play from the transport window and the default reverb will start playing along with the track. You can select a popup preset or turn the pan controls to adjust the effect in the effects window.
- if you want to remove the effect, highlight the name in the effects window and hit the delete key of the keyboard or clear from the menu.
you can also add more than one effect to a track......have reverb, flanger and EQ all at once.
Once you get used to doing this, you can do the same thing on an aux..... and this is where the real power and usefulness of effects and aux comes in.... because you can have one reverb and place it on multiple tracks at different strengths saving CPU power.

and download the "Quick Aux Setup Tutorial" at the bottom of the page.
It is VERY step by step....so you shouldn't have any problem....(but it was written when the mixer window was the instruments window).
It is also written as a demo using the AUMatrixReverb so it shouldn't be too different to what I wrote above.
