No problem, I thought, as I couldn't see why Flare wouldn't support the .HTML file extension.
But when I changed the file extension from .HTM (which is the Flare default) to .HTML, I get the following error...
Now it turns out that this is actually just a minor annoyance as Flare works just fine with all of my file extensions changed from .HTM to .HTML. I get no errors when generating and my projects work absolutely beautifully whether I use one extension or the other.
But I'm still wondering... why do I get this error if it really isn't a problem?
Shouldn't Flare "support" .HTML as much as .HTM? Or is this some internationally-accepted standard that I'm violating somehow?
This really isn't worthy of a bug report (or is it?) but I thought I'd toss it out to the general community for comment.
Thoughts? Impressions?
