Safari (5.1.7) seems to do everything right - I click the Upload button, choose Files, then in the dialogue box I find the file I want, select it, the Choose button turns blue and I click it. Then... nothing! The file doesn't upload.
So I tried Firefox, and after selecting the file, I got the
Upload Progress◧ 75%
box and the file was uploaded to my Gmail Drive.
Why doesn't Safari do the job?
