wpf controls - Access key getting selected even we did not press 'Alt' key in WPF

Question

I have WPF application which is having tool bar. In tool bar I have some user controls as tools.

I have set access key to each control, it is working fine.

The issue is: If I click a user control(which is consist of Button and Label, I have set access key for Button) the given task is completed, but when I press any access key without pressing 'Alt' key then it is getting selected.

Any ideas?

As of .Net 4.5 you can configure this behavior with the CoreCompatibilityPreferences.IsAltKeyRequiredInAccessKeyDefaultScope property. To change the access key behavior so that they will only fire when Alt is pressed set it to true.

CoreCompatibilityPreferences.IsAltKeyRequiredInAccessKeyDefaultScope = true;

As the documentation states this must early in the app. Setting it will throw an exception after it has been read.
