When I open the Security Editor, i have a localization error message. After closing the error, the security editor is open and the labels are in French!

I know that my desktop is in French (Regional Settings in "French - Canada"), but I am used to code in English. Since I did not set anything for the Localization & Messages (My broken rules are in french now when using the Security Editor), it is a bug in the framework or do i need to set something to avoid that error?
