Rodder,
I am not sure if what I have done / am doing is a "fix" or if I have done something else that corrected it, but, just in case, try this...
I installed the MaZEdit program in my program files. I then deleted all the language files (except Spanish and English) from the library. I retained the Spanish (Espanol) library as that is the default language file and the English library file as that is the one that I want to use. Then, I did NOT create a shortcut to the application file on my desktop. I opened it directly from the program file.
So far, it hasn't opened back up in any other language other than English for me. But, I haven't tested this very long, just 4-6 weeks so far. So, I may be a little premature in any evaluation. If you would like to try it on your system, that is my notion so far.
