This my first post in the Community looking for help.
The following sounds as a bug in the Spanish support of v10.20.
My OS is a Windows 8.1 Spanish version.
It seems that the installation procedure of V10.2 recognized this fact and set the «Edit>Preferences>Interface>Language» to «Spanish».
Since I am used to the English configuration since the very beginning (v2.1) and I prefer to work with the English version of the front end, the first thing I did after bumping into the Spanish interface was to reset «Edit>Preferences>Interface>User Interface Setting>Language» drop down to «English».
But for some reason, I think, V10.2 got messed up and though it retains the «English» value in the «user interface setting»> Languaje, the Menu Item keeps presenting partially the «Spanish» wording, I say partially because some of the drop-down menus appear in English and some others in Spanish, although not always; «not always» means that the same options appears different (either English or Spanish) in different Mathematica v10.2 sessions. I found this erroneous behaviour in the drop-down menu tab «File (English)/Archivo (Spanish)», I cannot tell about any other tab yet, although some of the basic choices as «messages» and «Find and Replace» under the drop-down tab «Ventana/windows» keep appearing in English intermixed with other options in Spanish. Curiously the option (in Spanish) «Edit>Preferencias
» takes to a window «Preferences» with all the stuff in English.
I sent the issue to Wolfram customer service during the trial period of V10.2, asking for a way to reset the interface to English and was told to come to the Community looking for help. They added that the problem could be due to the fact that I had had a previous Spanish package language (?) in a previous version, but In fact I have never had such a thing, and in any case V10.2 should be isolated from the rest of the stuff in my computer.
In summary, I think,
In summary, I want my menu Items in English, How to make the Matematica v10.2 to do it so?
Perhaps something in the OptionInspector? I checked out the Global Preferences>International Options>Language and found it is set to «English»
I will appreciate your help.
