Autocomplete, Monodevelop, and String/string

I'm currently using UnityScript to do my coding. And I am having issues with Autocomplete changing my variable of type 'String' (with a capital S) into 'string' (lower case s) after I type it out. Which causes me to have to go back and re-type the word with a capital S. For example:

 var temp : String = "foo";

instantly becomes

 var temp : string = "foo";

At which point, Unityscript complains about it since lower-case 'string' is not a variable type.

Is there anyway to "teach" the Autocomplete to accept the capital S spelling of 'String' so that it won't change it?
