For example, you install a MOD (and, as said, there are others) like : Language Select. You wish to change the language from the dropdown form (for instance, when editing the home page in this case). Then, you hit refresh, the refresh warning window will appear (the one from your browser) and we have to hit "ok" each times (which, I must say, is very annoying). That said, there are no other ways than re-typing the URL "or" accepting the refresh window info for avoiding these boxes. Which is why, the home link has been added above - in order to get rid of these annoying warnings.
