i.e. if the menu is Alter with the Mnemonic T ("Al&ter") and the accellerator is control-A, an underline appears both under the O in the label "Open" and under the t of the accelerator label "Ctrl+A".

Mnemonic should only appear in the label, not in the accelerator.

Don't know if this is a Menu-utilities bug or a Swing or AWT bug. If this is a Swing bug, please change to category java, subcategory classes_swing, and change the release in the customer call info to 1.0.2.
