Re: Frontpage default file type
You don't have to rename it after saving it.
When you go to file and save as, just stick an 'l' in front of .htm to make .html and it should save as that IIRC.
Not a really fix, but just worked for me (not that I use FP though). I know in Dreamweaver there is an option to specify what file extension you want to use but I can't seem to see one in FP.
