Hello all, yes another post...

I would like to know how I can edit .HTMLX files in Dreamweaver MX's Design View?

After I create a .HTMLX document and try to reopen it or anytime I try to open a .HTMLX file in general, the Design View button is greyed out, I'm defaulted to Code View and that's it.

Any direction or advice would be greatly appreciated again.

Thanks!
