I can preview my site int he browser just fine.
But when I go to export it the Export menu is disabled.
What have I done?
Have you quit and gone back in?
Yes I have quit and gone back in.
I have solved the problem by saving to a dropbox folder. Driving home from the office and loading the project on my mac at home. — Think its a bug?
Sounds like it. Report it through the menu option so @Norm knows.
